Segmentation fault during the building process.
GCC pass all stage1 and then dies at the first 
invocation of the newly created 'cc1'.

which is for me: (dir: objdir/gcc/gcc)
./xgcc -B./ -B/usr/local/gcc/i686-pc-linux-gnu/bin/ -isystem /usr/local/gcc/i686-pc-linux-gnu/include -S tmp-dum.c

cc1: Internal error: Segmentation fault.
   Please submit a full bug report.
   See <URL:http://www.gnu.org/software/gcc/bugs.html> for instructions.
make[2]: *** [s-under] Error 1
make[2]: Leaving directory `/home/olivier/buildtmp/gcc/gcc'
make[1]: *** [stage_c] Error 2
make[1]: Leaving directory `/home/olivier/buildtmp/gcc/gcc'
make: *** [bootstrap] Error 2
>How-To-Repeat:
Very simple, on my platform: Debian 2.2, i686-pc-linux-gnu
any attempt to build the compiler from CVS:

So the following:
mkdir objdir
cd objdir
../cvs/gcc/configure --prefix=/usr/local/gcc --enable-shared --enable-languages=c++
make bootstrap

will segfault at the first invocation of the newly created
'cc1'. This appends just after the first pass (stage1).
>Fix:
Unfortunatelly, I do not have any!
I am very sorry!
