So I have an open-source project that I've been working on.  LDC has been my compiler of choice on Windows (32-bit) for a while now, but a couple of commits back it started behaving weird.  The program compiles just fine without errors, but when attempting to run the program a segfault occurs.  This does not happen when compiling with DmD.

GDB has been unhelpful with trying to locate the source of the problem, and my co-conspirator has been unable to help because he's on Linux and doesn't get any errors.  So, the problem is either with LDC or with the Visual Studio linker, and I don't know how to diagnose from here.

The commit that caused the problem can be found on my GitHub here:

Try the Visual Studio debugger (and obviously build with -g); the VisualD plugin might help too.

Not so sure about that, DMD isn't exactly bug-free. ;) Are you using matching LDC and DMD versions?
Wrt. linker, you can also give LLD a shot by adding `-link-internally` to the LDC command line.
