It's worse than that. Any use of longjmp() will cause undefined
behavior in C++. That's because each C++ object's destructor will not
be called (possibly other reasons, too).
I suggest looking at the PL/V8 code for an example of how to make C++
code work as a Postgres extension. IIRC they've made specific
trade-offs that might be useful for Jacques' use case too.
