In general gcc is used in those kinds of systems, and we manually turn off RTTI with -fno-rtti due to the incredible slowness of typeinfo and dynamic_cast. Sorry I mispoke there! Thanks for pointing out the thread-safety issue. I'm doing another pass on the next version to try to spot other thread safety issues.

You are now thread-unsafe. You will need to add a mechanism to protect that static data. Hi, been following this interesting group of articles.

Could you enumerate compilers where you have found this problem? Our reflection system relies in RTTI (static, we compile with RTTI disabled) too.

This is an important change from your last post. You are now thread-unsafe. You will need to add a mechanism to protect that static data.
