A fix is available
APAR status
Closed as program error.
Error description
If a program calls setjmp/longjmp, it will not be possible to use Ctl-C to exit the program any more, since SIGINT will be blocked.
Local fix
Using _setjmp and _longjmp can avoid the issue.
Problem summary
The signal mask is not restored correctly by longjmp() and siglongjmp(). In most cases, SIGINT becomes blocked and the user cannot quit the program using CTRL+C.
Problem conclusion
longjmp() and siglongjmp() restore the signal mask correctly.
Temporary fix
