Hi,

We are seeing sporadic crashes since we migrated to MCJIT on Win64. The
same tests pass without issues on Mac64 and Linux64. The issue is this
assertion failure in RuntimeDyldELF.c:

  RealOffset <= INT32_MAX && RealOffset >= INT32_MIN

I haven't managed to successfully catch the failure in Visual to try and
debug it. Any tips on how to make progress?

Oh, and we're on LLVM 3.5.

Thanks.

Ram
