ICE in cpp with

[Andreas Jaeger <aj at arthur dot inka dot de>]

Compiling the current CVS version on mipsel-linux I get an ICE in cpp
during bootstrap:

echo "int xxy_us_dummy;" >tmp-dum.c
./xgcc -B/opt/gcc-2.96/mipsel-unknown-linux-gnu/bin/ -B./ -isystem /opt/gcc-2.96/mipsel-unknown-linux-gnu/include -S tmp-dum.c
xgcc: Internal compiler error: program cpp got fatal signal 11

I'm appending below some output from gcc and gdb in the hope that this
gives somebody an idea how to fix this.

warning: Hit heuristic-fence-post without finding

warning: enclosing function for address 0x282ab138
This warning occurs if you are debugging a function without any symbols
(for example, in a stripped executable).  In that case, you may wish to
increase the size of the search with the `set heuristic-fence-post' command.

Otherwise, you told GDB there was a function where there isn't one, or
(more likely) you have encountered a bug in GDB.
