Yes. Only on Linux/ia32. Linux/x86-64 passed that failure
point.

Ok, I'm trying to reproduce and get genmodes.i.

Hm, I'm into stage2 and genmodes was already built and executed fine - so,
I don't seem to be able to reproduce it right now.

How did you configure?  I did

/space/rguenther/tramp3d/trunk/configure --enable-languages=c --disable-nls
--with-build-time-tools=/abuild/rguenther/tools32/usr/bin

which configures for i686-pc-linux-gnu for me.

Thus, please somebody attach genmodes.i that is miscompiled.

Configuring gcc with

../src-trunk/configure --enable-clocale=gnu --with-system-zlib --enable-shared
--with-demangler-in-ld

may see it in stage2.

Hmm, building genmodes.o with -save-temps makes the segfault go away...
