Description Paul Jakma 2005-03-14 08:54:20 UTC 
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.7.3) Gecko/20041020 Galeon/1.3.19

Description of problem:
- retrieve the qemu CVS sources 
  (the attached files are from CVS from 20050314 0830GMT CVS, but the problem
   has been occuring for a while now)
- try compile it on FC3 x86_64 
  (I havn't tried on i386)
- Get segfault in qemu's target-i386/op.c file:

gcc -Wall -O2 -g -fno-strict-aliasing -falign-functions=0 -fno-reorder-blocks -fno-optimize-sibling-calls -I. -I/home/paul/cvs/qemu/target-i386 -I/home/paul/cvs/qemu -D_GNU_SOURCE -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -I/home/paul/cvs/qemu/fpu -I/home/paul/cvs/qemu/slirp -c -o op.o /home/paul/cvs/qemu/target-i386/op.c

Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://bugzilla.redhat.com/bugzilla> for instructions.
Preprocessed source stored into /tmp/ccTRyOgP.out file, please attach this to your bugreport.

See attached C source file and the preprocessed source which gcc advised me to post to bugzilla.
