ICE in gcc-ss-20001016

[David Ronis]

I encountered the following ICE when doing a bootstrap build on an
i685-linux(2.2.17)-gnu(2.1.3) system.  

./xgcc -B./ -B/usr/i686-pc-linux-gnu/bin/ -isystem /usr/i686-pc-linux-gnu/include -dumpspecs > tmp-specs
mv tmp-specs specs
echo "int xxy_us_dummy;" >tmp-dum.c
./xgcc -B./ -B/usr/i686-pc-linux-gnu/bin/ -isystem /usr/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.

I configured with: --host=i686-pc-linux-gnu --prefix=/usr
--with-gnu-as --enable-shared --with-gnu-ld and used the default
CFLAGS for the bootstrap.

My system compiler is gcc-2.95.2 and I'm using binutils-2.10.91.

The last snapshot built under identical conditions.

I've rerun the command with -save-temps and -v flags.  I get:

 ./xgcc -v -v -v -save-temps -B./ -B/usr/i686-pc-linux-gnu/bin/ -isystem /usr/i686-pc-linux-gnu/include -S tmp-dum.c

No .s file was created and the tmp-dum only contains the lines:

    # 1 "tmp-dum.c"
    int xxy_us_dummy;

Finally, running cc1 manually from the command line SIGSEGV's,
irrespective of arguments.
