Mixed Case benchmark fails on Mac (Clang only)

[mavam]

While I was on a mission to compare Clang and GCC benchmarks, I encountered a crash when running the Mixed Case benchmark.

GCC:

./bin/mixed_case event-based 10 10 42 1  14.96s user 0.17s system 188% cpu 8.038 total

Clang:

terminate called after throwing an instance of 'std::runtime_error'
  what():  uniform_type_info::by_type_info(): std::__1::basic_string<@i8,std::__1::char_traits<@i8>,std::__1::allocator<@i8>> is an unknown typeid name

This bug disappeared as well after reinstalling the whole toolchain. Sigh.
