FWIW, there is a caveat in the OpenBSD man page concerning the use of

"Use of longjmp() or siglongjmp() from inside a signal handler is not as
 easy as it might seem.  Generally speaking, all possible code paths
 between the setjmp() and longjmp() must be signal race safe, as discussed
 in signal(3).  Furthermore, the code paths must not do resource
 management (such as open(2) or close(2)) without blocking the signal in
 question, or resources might be mismanaged.  Obviously this makes
 longjmp() much less useful than previously thought."
