I've not tried it, but I'm very surprised that symbol is needed on
Linux. As far as I know only iOS uses the setjmp/longjmp
exception-handling style.

Of course, it could be a very poorly named but still generic function
(or an alias or something). But I'd still start my search by looking
into just what thinks it wants that and why.

Good luck!

Tim.
