I think that this technique is pretty gross. Why not implement some kind of
exception handling instead? I've been working on a small exception handling
library which which is written in portable C and gives you things like: nested
try-catch regions which specify a list of what they catch; exceptions that have
code and group ID's so groups of exceptions can be caught as well as specific
exceptions; clean-up handlers for releasing resources during unwinding; passage
of arbitrary dynamic data from throw to catch site, etc.  With POSIX thread
support enabled, each thread has its own exception stack context, including its
own own allocator routines and unhandled exception catcher.
