Well, an AthlonGCC bug might be the cause, but I've had no problems
with any other app compiled with it.

Anyway, compiled in debugging info, all other flags the same, here's
the output I get from gdb:

(gdb) r mkconfig.rb
Starting program: /downloads/ruby-1.6.1/miniruby mkconfig.rb
warning: Unable to find dynamic linker breakpoint function.
GDB will be unable to debug shared library initializers
and track explicitly loaded dynamic code.

Program received signal SIGSEGV, Segmentation fault.

I've also been told that this sounds very similar to a problem being
had by a couple of people with Tru64.

Hope that helps some.....
