Linux 2.4.20 SMP, x86, Debian 3.0_r1/woody,
gcc-snapshot_20030118-1_i386.deb
>Description:
When compiling the source with -fstrict-aliasing, the following ICE occurs:
/usr/lib/gcc-snapshot/bin/g++ -c -Wall thread-log.ii -o z.o -fstrict-aliasing
../src/kern/ia32/thread-log.cpp: In static member function `static void
Thread::hook_ipc_vector()':
../src/kern/ia32/thread-log.cpp:301: internal compiler error: in
set_mem_alias_set, at emit-rtl.c:1932
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://www.gnu.org/software/gcc/bugs.html> for instructions.
Leaving -fstrict-aliasing out, it compiles.
I also tried several previous versions from the 3.3 branch
which gave the same errors.
>How-To-Repeat:
/usr/lib/gcc-snapshot/bin/g++ -c -Wall thread-log.ii -o z.o -fstrict-aliasing
>Fix:
Don't compile with -fstrict-aliasing or -O2 or higher.
It works with gcc-3.2.2 and gcc-2.95.4.
