Review comment:
Does this work on x64 windows?
Just an educated guess: from the looks of it, and @cyb70289 's comment, it
looks like an incompatibility between clang-cl and MSVC's runtime libraries --
clang-cl generates calls to __*ti3() functions expecting them in the runtime
libs. Compiler-rt does provide them, but MSVC's libraries do not.
