digitalmars.D.ldc - Having issues chasing down a segfault

reply Philip Pavlick <philip swash.link> writes:
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:

Please file an issue on github with the compiler version:

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.
