The symbol type_info introduced by the C++ standard library into the global scope causes clashes with user-defined symbol of the same name.

Thank you for reporting this. When support was added for these templates, there were not a proper namespace support in the compiler. Changing this right now is not possible because of backward compatability. We would really like to fix this but unfortunately without other substantial changes we won't be able to do so.

Thanks,
