Preprocessed source file.
I was attempting to build Python v.3.5.2 with SafeStack enabled when the
following assertion failure occurred. I have attached the preprocessed source
and the run script. Here is the backtrace:
clang-4.0: /home/mlemay/llvm/llvm/lib/CodeGen/SafeStackColoring.cpp:217: void
llvm::safestack::StackColoring::calculateLiveIntervals(): Assertion
`!Started.test(AllocaNo)' failed.
