I'm having issues with DMD returning exit code -11 rather than compiling my project. I have no idea how to debug this, I'm using Mac OS X 10.9.4 with latest git DMD tagged 2.066, and this project:

https://github.com/etcimon/event.d

When I hit `dub run`, I get the exit code. Not sure why or where the problem comes from, I can't get GDB to run on the mac (something about Mach task port error in gdb), and dmd DEBUG gives no additional info. Any ideas?

I managed to get gdb running, here's what I get:

Here's with debug symbols in DMD

Program received signal SIGSEGV, Segmentation fault.

The tempdecl->parent is being accessed even though it may be null in :7329 :
  ::error(loc, "%s %s.%s does not match any template declaration",
tempdecl->kind(), tempdecl->parent->toPrettyChars(), tempdecl->ident->toChars());
