I just tested LDC and GDC, and they aren't compatible either. Probably
because they each ship with their own version of Phobos, and link with
their own C runtimes that aren't compatible with each other.

I think it's generally accepted that you have to use the same compiler
to compile an entire program.  I've never heard of it being considered a
bug that the output of two different compilers are incompatible.  It'd
be great if it could somehow still work anyway, but generally I don't
think it's expected to.

And I would think it shouldn't matter which compiler you use as long as
your code doesn't depend on compiler-specific features; you could just
recompile with a different compiler if need be, and go along your merry
way.
