[antlr-interest] C++ exceptions in the ANTLR3 C target

Now that the C target can be built by a C++ compiler, I've been trying
to throw C++-style exceptions (as opposed to the exception system
internal to ANTLR's C target) from within embedded actions.
My grammars build successfully, and the exceptions seem to behave as I'd
expect at runtime. However, I suspect I'm leaving myself open to
undefined behaviour; are C++ exceptions within the C output actually
supported, or is it merely co-incidence that nothing horrendous has
My main fear would be memory leaks, but I'm not 100% sure if this is
happening or not.
