This looks like a miscompilation of the stage2 compiler. Linux is fine so I'm
afraid nobody will look into this in the immediate future.
Please try with newer snapshots.

It will be fine if the fix goes into the latest snapshot.

It still fails with snapshot gcc-4.7-20110716. I am downloading
gcc-4.7-20110730 at this minute. I will report the result of it once
the build is complete.

It fails once again. However, it fails at different point (in stage 2)
and with different error message compared to the past failure. Below
is the error message:

The configuration --enable-languages=ada --without-build-config
--disable-werror was used.
Now it causes gcc to fail when configuration --enable-languages=ada,c,c++ is
used. Below is the trailing error message.

Hmm, this is due usage of "%lld" in printf-formatter. Does following patch fix
your issue?

with snapshot gcc-4.7-20111105, there are syntax errors in adainit.c,
initialize.c, seh_init.c and tracebak.c. These files are located at /gcc/ada
directory which is part of Ada compiler.
I fixed these errors with my own ways (mostly adding explicit conversion), the
bootstrap went further and finally crashed with a bug box as originally report
as shown below. Thus, implicit-zee.c may not be an issue regarding this
snapshot.

I did encounter the build failure reported in comment #6 (unknown conversion
type character 'l' in format) on i386-pc-mingw32, and the patch given in
comment #7 did fix this failure for me.
A similar solution is also needed in gcc/ira-color.c
(print_hard_regs_subforest), where %lld is also used.
This allowed the build to continue to the point where I could reproduce the
failure described in comment #8.

Also, in gcc/config/i386/i386.c (ix86_print_operand), where %08llx is used.

Although, due to additional warnings in the Ada build, I had to force
--disable-werror at this point.

Created attachment 25922
--> http://gcc.gnu.org/bugzilla/attachment.cgi?id=25922
Debug log of PR49084
The cause of the access violation is due to an attempt to pass a null string
pointer to asprintf in internal_error_function
(gcc/ada/gcc-interface/misc.c:290):
(gdb) frame 2
#2 0x0042bfad in internal_error_function (context=0x1a15800, msgid=0x11e08df
"in %s, at %s:%d", ap=0x722faa4) at
../../../../gcc-svn-fixada/gcc/ada/gcc-interface/misc.c:290
290 asprintf (&loc, "%s:%d", s.file, s.line);
(gdb) l
286 s = expand_location (input_location);
287 if (context->show_column && s.column != 0)
288 asprintf (&loc, "%s:%d:%d", s.file, s.line, s.column);
289 else
290 asprintf (&loc, "%s:%d", s.file, s.line);
291 temp_loc.Low_Bound = 1;
292 temp_loc.High_Bound = strlen (loc);
293 fp_loc.Bounds = &temp_loc;
294 fp_loc.Array = loc;
(gdb) p input_location
$1 = 0
(gdb) p s
$2 = {file = 0x0, line = 0, column = 0, sysp = <optimized out>}
It remains to be seen why input_location is zero. Maybe it's too early in the
process execution?
Earlier in the stack trace, there is an assertion triggered in gigi
(ada/gcc-interface/trans.c:300):
(gdb) fr 6
#6 0x00491875 in gigi (gnat_root=1707, max_gnat_node=2431, number_name=1656,
nodes_ptr=0x7950020, next_node_ptr=0x78b52f8, prev_node_ptr=0x78e6050,
elists_ptr=0x7708e78, elmts_ptr=0x77094d0, strings_ptr=0x7734818,
string_chars_ptr=0x77320f0, list_headers_ptr=0x78a9760, number_file=3,
file_info_ptr=0x722fb9c, standard_boolean=12, standard_integer=27,
standard_character=72, standard_long_long_float=67,
standard_exception_type=1281, gigi_operating_mode=0) at
../../../../gcc-svn-fixada/gcc/ada/gcc-interface/trans.c:300
300 gcc_assert (Nkind (gnat_root) == N_Compilation_Unit);
(gdb) l
295 String_Chars_Ptr = string_chars_ptr;
296 List_Headers_Ptr = list_headers_ptr;
297
298 type_annotate_only = (gigi_operating_mode == 1);
299
300 gcc_assert (Nkind (gnat_root) == N_Compilation_Unit);
301
302 /* Declare the name of the compilation unit as the first global
303 name in order to make the middle-end fully deterministic. */
304 t = create_concat_name (Defining_Entity (Unit (gnat_root)), NULL);
(gdb) p gnat_root
$3 = 1707
(gdb) p (Nodes_Ptr[(gnat_root) - 0].U.K.kind)
$4 = 17 '\021'
It seems Nkind (gnat_root) is N_Op_Add (17) for some reason.
BTW this is trunk (svn 181738), with the stage 2 compiler (this bug is not
manifest in the stage 1 compiler).
Full debug log is attached.

Zero is UNKNOWN_LOCATION. The problem is probably that the location mapping
isn't initialized yet. What happens if you move the block in gigi:
gcc_assert (Nkind (gnat_root) == N_Compilation_Unit);
/* Declare the name of the compilation unit as the first global
name in order to make the middle-end fully deterministic. */
t = create_concat_name (Defining_Entity (Unit (gnat_root)), NULL);
first_global_object_name = ggc_strdup (IDENTIFIER_POINTER (t));
to after the immediately following loop?

Use 'call pn(gnat_root)' instead.

This very likely means that the stage 1 compiler has miscompiled the stage 2
compiler.

It seems OK to me on the Ada side. I wonder what makes it trigger the assertion
gcc_assert (Nkind (gnat_root) == N_Compilation_Unit)
Maybe the C accessor "Nkind" is not working well for some reason?

Yes, there is something really weird going on at the interface between C and
Ada.
Unfortunately I don't seem to be able to reproduce on Linux. Could you see
what object code has been generated for the line
gcc_assert (Nkind (gnat_root) == N_Compilation_Unit);
in stage1-gcc/ada/trans.o and prev-gcc/ada/trans.o?

--- Comment #16 from Cesar Strauss <cestrauss at gmail dot com> 2011-12-10 23:03:13 UTC ---
As can be seen in the assembler code above, the Ada compiler thinks the Node
structure is 32 bytes in size, while the C compiler thinks its size is 36
bytes.
The culprit is the struct Flag_Word (gcc/ada/atree.h:116), included in Node,
which increased from 4 bytes to 6 bytes:
struct Flag_Word
{
Boolean flag73 : 1;
Boolean flag74 : 1;
Boolean flag75 : 1;
Boolean flag76 : 1;
Boolean flag77 : 1;
Boolean flag78 : 1;
Boolean flag79 : 1;
Boolean flag80 : 1;
Boolean flag81 : 1;
Boolean flag82 : 1;
Boolean flag83 : 1;
Boolean flag84 : 1;
Boolean flag85 : 1;
Boolean flag86 : 1;
Boolean flag87 : 1;
Boolean flag88 : 1;
Boolean flag89 : 1;
Boolean flag90 : 1;
Boolean flag91 : 1;
Boolean flag92 : 1;
Boolean flag93 : 1;
Boolean flag94 : 1;
Boolean flag95 : 1;
Boolean flag96 : 1;
Short convention : 8;
};
On MinGW, the bitfield packing convention has changed in GCC 4.7: it now
follows the Microsoft compiler (-mms-bitfields). Since the size of the
"convention" field (16 bit short) is different from the previous one (8 bit
unsigned char), padding is added until it starts on a new 16 bit boundary.
Indeed, rebuilding GCC with make 'BOOT_CFLAGS=-g -O2 -mno-ms-bitfields' allows
the build to proceed to completion. Changing Short to Byte in Flag_Word also
works.

Let's do the latter. Would you mind posting a patch on gcc-patches? TIA.

Hmm, other way to solve this might be to add to structure the optional

Thanks. Let's avoid gratuitous non-portable stuff though.
