../../gcc/gcc/genmodes.c: In function `emit_mode_mask':
../../gcc/gcc/genmodes.c:964: internal compiler error: Bus error
The configure command was:
../gcc/configure --with-gnu-as --with-as=/opt/gnu/bin/as --enable-shared --with-
local-prefix=/opt/gnu --prefix=/opt/gnu/gcc/gcc-3.4 --enable-debug=no --disable-
nls --enable-checking="misc,tree,rtl,rtlflag,gc,gcac,fold" &&
The problem does not occur if `--enable-checking' is not specified.
The stack trace is:
Program received signal SIGBUS, Bus error.
md5_process_block (buffer=0x7aed3f6e, len=64, ctx=0x7eff1500)
at ../../gcc/libiberty/md5.c:325
325 OP (A, B, C, D, 7, (md5_uint32) 0xd76aa478);
#0 md5_process_block (buffer=0x7aed3f6e, len=64, ctx=0x7eff1500)
at ../../gcc/libiberty/md5.c:325
#1 0x00af0064 in md5_process_bytes (buffer=0x7aed3fae, len=96, ctx=0x7eff1500)

ht=0x40079aa0) at ../../gcc/gcc/fold-const.c:8408
...
The fault occurs because of a misaligned load for a word:
0x00af0184 <md5_process_block+156>: ldw 0(,r18),r20
(gdb) printf "0x%x\n",$r18
0x7aed3f6e
This is buffer address passed to md5_process_block from
md5_process_bytes.
The same error occurs on hppa-linux but the exception is
handled by the kernel unaligned handler.

It does not happen without --enable-checking because md5 is not used. The problem is that
md5_process_block believes it is okay to have unaligned words. This will effect 3.5.0 also if PCH
and includes are used and the buffer is not word aligned.

This change breaks building Cygwin, and probably anything else that uses
libiberty outside of gcc, because 'md5uint_ptr' is only defined in the gcc tree:

I can build the latest CVS binutils on x86_64-linux. Please make sure
you have the include files that correspond to the libiberty you're
using; you can't mix and match them. If you are using a newer md5.c
than md5.h you're bound to have problems.

*sigh* Yes, you're right. I had cvs upped in libiberty and not include. Sorry
for the noise.
