Make sure you're compiling with -gc (not -g), if that's still happening 
then one of two things needs to happen:

1) A bug gets filed to the gdb team with the relevant object files so 
they can reproduce it/fix it
2) It needs narrowing down so that dmd can work around it.

Alternatively you could compile with ldc or gdc as they will produce 
different debug information and probably won't cause gdb to crash.
