So I figured out the python issue. Host::GetLLDBPath() is broken. It was failing for me because I am building in Release mode. It only works in Debug mode by luck :) The problem is lines 1035+ in source/Host/common/Host.cpp. llvm::Twine should only be used
for temporary objects! See <a href="http://llvm.org/docs/ProgrammersManual.html#dss-twine" target="_blank">
http://llvm.org/docs/ProgrammersManual.html#dss-twine</a><br>

I have attached a patch this fixes the issue. I haven't found time to investigate my other issue yet.<br>
