Fixed; the bug is latent in 4.3.
The testcase should be added to 4.3 to make sure that it remains latent

Well, ISTR something about local variables need to be marked volatile if you
use setjmp/longjmp. Is psim really in compliance with what the standard says
here? See 7.13.2.1/3

C standard guarantees that automatic variable only with volatile will be
restored after longjmp. Gcc puts volatiles on stack and don't use pseudos for
them. So they will be never
