 Thanks for the information Reid!

I am entirely new to Clang and was unknowingly targeting the Itanium ABI.
By switching to the the Microsoft ABI with clang-cl the problem went away.
:-)

Unfortunately, I instead encountered many RTTI-related compiler issues as
you mentioned. This is a bit disappointing, since it seem like neither ABI
will work for me at the time being.

My primary motivation for testing Clang was to evaluate the static
analyzer. Run-time issues like exceptions, missing debug info etc. is
therefore not a concern for me. What matters is to be able to parse/compile
the code.
