[Bug c/13187] New: Bug in optimizer?

["kvo at ilt dot kharkov dot ua" <gcc-bugzilla at gcc dot gnu dot org>]

It is impossible to successfully compile the 'gsl' system
(sources.redhat.com/gsl). Compiler gives message:
---------
gcc -DHAVE_CONFIG_H -I. -I. -I.. -I.. -I.. -O2 -march=pentium3 -mfpmath=sse
-msse -c oper.c  -fPIC -DPIC -o .libs/oper.lo
In file included from oper.c:21:

  I think, it is optimizer' bug.
