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());
