Subject: When do I need -fnon-call-exceptions?
Date: Wed, 7 Jun 2023 19:08:01 +0200	[thread overview]
Message-ID: <trinity-c6ee9039-f130-4c39-9346-892ab24ab654-1686157681645@3c-app-gmx-bap67> (raw)

I wrote some simple program that set a signal handler for SIGFPE, throws a C++ exception in the signal handler
and catches the exception.
I compiled with and without -fnon-call-exceptions (on x64 Linux).
In both cases, the result was the same: the exception was caught and the destructors were called as expected.
I also tried "-fno-non-call-exceptions -fexceptions" and got the same result.

My question: when do I really need -fnon-call-exceptions?
Is there some simple program where I can see the difference whether it is on or off??

Helmut
