514 sigsegv (or other trouble) in user code signal handler catches the signal,
515 which then "appears" in the monitor thread (when the monitor executes raise()
516 function). Users see signal in the monitor thread and blame OpenMP RTL.
517
518 Grant said signal handling required on some older OSes (Irix?) supported by
519 KAI, because bad applications hung but not aborted. Currently it is not a
520 problem for Linux* OS, OS X* and Windows* OS.
521
522 Grant: Found new hangs for EL4, EL5, and a Fedora Core machine. So I'm
523 putting the default back for now to see if that fixes hangs on those
524 machines.
525
526 2010-04013 Lev: It was a bug in Fortran RTL. Fortran RTL prints a kind of
527 stack backtrace when program is aborting, but the code is not signal-safe.
528 When multiple signals raised at the same time (which occurs in dynamic
529 negative tests because all the worker threads detects the same error),
530 Fortran RTL may hang. The bug finally fixed in Fortran RTL library provided
531 by Steve R., and will be available soon. */
