--- Comment #18 from Baber Nawaz <baber.nawaz at hotmail dot com> ---
Here is a testcase with ordinary C++ exceptions, with no traps, signals
or -fnon-call-exceptions:
int x;
[[gnu::noipa]] void f () {}
void t () { throw 0; }
struct S
{
~S () { if (--x == 0) { x = 1; f (); } }
};
[[gnu::noipa]] void g () { S s; t (); }
int
main ()
{
x = 2;
try { g (); } catch (...) {}
if (x != 1)
__builtin_abort ();
}
$ g++ -O1 pr85803-eh.C && ./a.out
Aborted
It aborts at -O1, -O2 and -O3 with 12.5, 13.4, 14.3, 15.2, 16.2 and trunk
(17.0.0 20261110) on x86_64-linux-gnu (Compiler Explorer builds), and
passes at -O0 and with -O1 -fno-tree-dse.
