[cfe-dev] Problems with Clang since upgrading compiler to Visual Studio 2015

Hi guys,

I'm having an issue with clang/llvm since I upgraded my compiler from
VS2013 to VS2015. I'm invoking clang programmatically to compile C++ source
files and up till now it has worked fine but since the upgrade and
recompiling all the clang/llvm libraries I'm getting some errors deep
inside the clang/llvm source without having changed any code on my end. The
problem I'm facing right now is an assertion being triggered in an llvm
class:

Assertion failed: HasHungOffUses && "alloc must have hung off uses", file
F:\Cla
nggit\llvm\lib\IR\User.cpp, line 44

Here is the complete call stack up till the assertion:

  ucrtbased.dll!_abort () Unknown

Here's hoping someone here can give me some guidance on resolving this
issue.

Thanks a lot for your time.
