[Bug c/13476] New: wrong code with -O3 -fPIC (segmentation fault)

["strasbur at chkw386 dot ch dot pwr dot wroc dot pl" <gcc-bugzilla at gcc dot gnu dot org>]

The following code is miscompiled (no error with -O2 -fPIC or
without -fPIC):
int xargc;
int iargcx() { return (xargc); }
int main(int argc, char **argv) {
xargc=argc; return (iargcx()); }

The function "iargcx" is responsible for the problem.
Command line: gcc -O3 -fPIC file.c, gcc configured with: ./configure --prefix=/usr --enable-languages=c --host=i386-slackware-linux --disable-libgcj --disable-nls
