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.
0 clang 0x09bfa4e9
