The following program causes an ICE with -fopenmp -fexceptions:
extern void bar (int);
void
foo (int n)
{
int i;
#pragma omp parallel for schedule(dynamic)
for (i = 0; i < n; i++)
{
bar (0);
@throw 0;
}
}

------- Comment #1 from pinskia at gcc dot gnu dot org 2006-11-23 23:04 -------
Actually you can reproduce the same ICE (with the same backtrace) with C++
code:
extern void bar (int);
void
foo (int n)
{
int i;
#pragma omp parallel for schedule(dynamic)
for (i = 0; i < n; i++)
{
throw 0;
}
}
So this is not specific to Objective-C any more.

------- Comment #2 from jakub at gcc dot gnu dot org 2006-11-26 19:16 -------
That's actually ICE on invalid, you can't throw out of a parallel region.
OpenMP 2.5, section 2.4 says:
"A throw executed inside a parallel region must cause execution to resume
within the same parallel region, and it must be caught by the same thread that
threw the exception."

------- Comment #3 from jakub at gcc dot gnu dot org 2006-11-29 20:21 -------
This is similar to PR27328 which was only fixed for omp parallel (and even then
only when not inlined or inlined at most once).
Started fixing these omp region with NULL region->exit and/or region->cond
issues today, but still have some to finish tomorrow.
