When writing the C code for the new regex module I thought that it

return an error code to /its/ caller.
That's called longjmp.
Automatic garbage collection would also have been nice.
alloca might help.
If you want proper exception unwinding, use C++, which
has it. "longjmp" is a hack from the PDP-11 era.
