[cfe-dev] Compiler crash on libclang with r171300

[Matthieu Monrocq]

Hello,

I was trying to compile the Release+Assert of LLVM + Clang at r171300 and I
hit an assertion building ~/llvm/tools/clang/tools/libclang/ARCMigrate.cpp
with the newly built clang (whilst the Debug build worked fine).

(and no I don't care to create a BugZilla account to report a bug...)


Console:

clang: ~/llvm/include/llvm/ADT/APInt.h:888: bool
llvm::APInt::operator==(const llvm::APInt &) const: Assertion `BitWidth ==
RHS.BitWidth && "Comparison requires equal bit widths"' failed.
