I'm a little confused.  What is crashing, the program you compiled, or
the compiler itself?

If it's the compiler, we deliberately disable core dumps because they
tend to be huge and less than helpful.  You should use -v -save-temps
to get the command line for the internal executable (cc1plus,
probably) that's actually crashing, then run it under the debugger.

If it's your program, check your user limits.  The core dump is
probably too big for them.

Note that egcs-2.91.66 is very old, you may wish to try gcc-2.95.3 or
a 3.0 prerelease snapshot.
