Instead of pounding a round peg into a square hole with C++, maybe the
path to pursue is GCC support for try/finally in C. You get most of
the semantics you are looking for, and someone as experienced as you
will know exactly what to do with the feature.

Lack of try/finally support means library often do awful things.
Asterisk was full of issues, like resource leaks, that try/finally
would have fixed. Eventually Asterisk moved to nested/inner functions
and trampolines. They silently lost NX stacks, which was a cure as bad
as the disease. It just moved problems around rather than fixing them.

Microsoft compilers support try/finally in C. I recall a GCC bug
report years ago asking for it, but it was declined.
