[Bug bootstrap/39849] New: stage1 compiler segfault during `make profiledbootstrap'

[dennis dot wassel at googlemail dot com]

I've tried to build the shiny new 4.4, but it seems the stage1 compiler has
hiccuped here:

--with-ppl=/localdata --with-cloog=/localdata

and built with

make CFLAGS='-O2' LIBCFLAGS='-g -O2' LIBCXXFLAGS='-g -O2
-fno-implicit-templates' profiledbootstrap

(on a side note: make died at host-linux.c because SSIZE_MAX is not defined by
my system, so I #defined it and carried on bootstrapping *without* cleaning)

Also, my ClooG config is a bit fishy, but this should not really concern xgcc,
should it?

Nevermind the typo in configure, it also segfaults with properly spelled
"--with-gmp=" instead of "--with-gp=".

[dennis dot wassel at googlemail dot com]

------- Comment #2 from dennis dot wassel at googlemail dot com  2009-04-23 08:27 -------
I tried the following things:

- #define SSIZE_MAX in host-linux.c as SHRT_MAX instead of LONG_MAX (as
suggested by an internal posix header on my system), to no avail.
- Just issue plain `make', instead of profiledbootstrap with custom flags,
still segfaults with the same file.
- Running xgcc in gdb, but it seems to lack debug information, so I cannot find
out the source of the segfault.

I'm out of ideas!

------- Comment #4 from dennis dot wassel at googlemail dot com  2009-04-27 10:38 -------
Today I tried configuring with --disable-bootstrap, again to no avail.

Please, could anybody just give me a pointer?
I cannot build gcc 4.4.0 with the gcc 4.3.3 on a mainstream Linux system
(Debian 4) - something has to be seriously wrong, given that gcc's bootstrap is
pretty die-hard, hasn't it?
Did I miss to include any relevant information?

I am now re-bootstrapping 4.3.3 to check if there is some kind of general
problem with my system - our admin recently installed an OS update, so maybe
that is the culprit...

The easy workaround is to use all or bootstrap instead of using
profiledbootstrap.

I re-profilebootstrapped 4.3.3 and it worked without problems (except for the
usual noise about my system headers missing SSIZE_MAX, but that is easily
fixed).

Now trying `make bootstrap' of 4.4.0.

------- Comment #7 from dennis dot wassel at googlemail dot com  2009-04-28 09:53 -------
Neither `make bootstrap' nor `make all' produce different results.
Btw: isn't `make' (which I tried earlier) equivalent to `make bootstrap'?

Back to square 1.

Do not set CFLAGS in

make CFLAGS='-O2' LIBCFLAGS='-g -O2' LIBCXXFLAGS='-g -O2
-fno-implicit-templates' profiledbootstrap

or specify your host compiler version.

It obviously works for me, you system seems to be messed up / special.

This ^ was only in my first iteration, and I've omitted it in the following
ones. My last (unsuccessful) attempt was a plain:

../gcc-4.4.0/configure --prefix=/localdata --program-suffix=-4.4.0
--enable-languages=c,c++,fortran --with-gmp=/localdata --with-mpfr=/localdata
--with-ppl=/localdata --with-cloog=/localdata
--enable-version-specific-runtime-libs

make

and nothing out of the ordinary.

> or specify your host compiler version.

My host compiler is gcc 4.3.3

gcc -v
Using built-in specs.
Target: i686-pc-linux-gnu
Configured with: ../gcc-4.3.3/configure --prefix=/localdata
--program-suffix=-4.3.3 --enable-languages=c,c++,fortran --with-gmp=/localdata
--with-mpfr=/localdata --enable-version-specific-runtime-libs
Thread model: posix
gcc version 4.3.3 (GCC)

Seems so, although it is a Debian 4 with an unknown amount of modifications by
our admin.
One symptom of specialness is the fact that neither the system nor the gcc's
headers define SSIZE_MAX, but I have a workaround for that (namely defining it
as SHRT_MAX in config/host-linux.c, if it is undefined).

Shall I dig around somewhere to find out the exact amount of my system's
specialness?

Is there a way to build the bootstrap compiler with debugging info, so I can
use gdb to figure out where the segfault happens?

PS: I think this *is* a regression, because I can build 4.3, but not 4.4.

[Bug bootstrap/39849] segfault for '__divtf3' during bootstrap and non-bootstrap install

[pinskia at gcc dot gnu dot org]

------- Comment #14 from pinskia at gcc dot gnu dot org  2009-05-04 15:00 -------
Yes slightly, it is trying to warn about something which is unitialized.  This
works for me on i686-linux-gnu.  Can you provide the preprocessed source?

Hi,

with Günther's last status report (2009-05-21) saying that there might be a
release in late June, is there any chance that this can be fixed till 4.4.1?

Thanks,
Dennis
