Here's for forced unwinding:

GCC's cxxabi.h also has abi::__foreign_exception, which appears not to 
have any public documentation. Here's the comment on top of this class:

A magic placeholder class that can be caught by reference to recognize foreign exceptions.

So it's pretty much the same as __forced_unwind.
