It might be possible to use protocols from libraries like this one:

http://libsigsegv.sourceforge.net/

AFAIK, this library has been created for CLISP.

I've had some good experience with it in (non-GC) C++ projects.

Currently, it probably collides with BDWGC signal handling or might
be dependent on a specific initialization order. But it might be
possible to figure out how to use it with BDWGC portably.
