Can you enlighten me as to what configuration you've confirmed 
this on?  I'm on
OSX: 10.9.5 (Mavericks)
GDB: GNU gdb 6.3.50-20050815 (Apple version gdb-1824) (building 
newer from source tends to fail to compile)
DMD: DMD64 D Compiler v2.067
GCC: Apple LLVM version 6.0 (clang-600.0.57) (based on LLVM 
3.5svn)

At best, I can _sometimes_ hit breakpoints when using Mono-D, 
it's inconsistent.  Even when a breakpoint is hit however, GDB 
only recognizes the current 'this' value; it doesn't recognize 
any frame / local variables other than 'this', global variables, 
etc., though it does recognize the call-stack at least.  When 
using GDB directly from a terminal, the only D source file it 
recognizes for the purpose of setting breakpoints or listing 
source code is app.d (which contains the main() entry-point).

Also have tried compiling with all combinations of -g, -gc, 
-debug, -gs, and -cov.  None seem to improve the situation.
