rechecked with r128456

the compiler is configure with --with-arch=i686 --with-tune=i586 i686-linux

I can reproduce it with -march=i686, not with -march=i486.

Still no luck there to reproduce segfault. These were my steps.

1. Configured latest SVN gcc in _clean_ build dir (on i686-pc-linux-gnu) using
../gcc-svn/trunk/configure --with-mpfr=/usr/local --enable-languages=c,c++
--with-march=i686 --with-tune=i586

2. ~/gcc-build-cpp/gcc/cc1plus -march=i686 -O2 -fPIC -g
libkformulalib_la.all_cc.ii

No problems here...

Ouch, that should be --with-arch=i686. Retrying...

Even with that change, I'm not able to reproduce the failure. Am I missing
something here?

sorry, I did make a mistake as well (omitted the -B when checking). The
segfault is gone with this revision.
