#3265 closed bug (fixed)

Custom signal handlers always receive SIGSEGV signals

Reported by: oco Owned by: bonefish
Priority: high Milestone: R1
Component: System/Kernel Version: R1/pre-alpha1
Keywords: Cc:
Blocked By: Blocking:
Platform: All


While tracking down remaining bugs in the freepascal test suite, i discover that custom signal handlers only received SIGSEGV signal instead of the one associated with the handler.

For example, in case of a zero divide, the signal handler associated with SIGFPE (8) only receive SIGSEGV (11).

This behavior is also true for C programs (see attached file test_custom_signal_handling.c).

I think this problem was introduced in hrev27757.

If i am not wrong, send_signal should send the real signal to the custom handler instead of SIGSEGV (see attached patch).
