The following code is accepted with -fopenmp although a return from a
parallel for loop is not allowed:
================================
void foo()
{
int i;
#pragma omp parallel for
for ( i=0; i<10; ++i )
return;
}
================================
When a value is returned, we get an ICE instead:
================================
int foo()
{
int i;
#pragma omp parallel for
for ( i=0; i<10; ++i )
return 0;
}
================================
bug.c: In function '__omp_fn.1':
bug.c:4: internal compiler error: in expand_expr_real_1, at expr.c:8307
Please submit a full bug report, [etc.]
The same holds for the C++ frontend; the ICE is just in a different position.

The C frontend seems to be fixed now. I get a sensible error message now for both testcases: bug.c: In function '__omp_fn.1': bug.c:6: error: invalid exit from OpenMP structured block Btw, should this really be __omp_fn.1? The C++ frontend remains broken, however: I get a sgefault now for both testcases. -- reichelt at gcc dot gnu dot org changed: What |Removed |Added ---------------------------------------------------------------------------- Component|c |c++ Keywords|accepts-invalid | http://gcc.gnu.org/bugzilla/show_bug.cgi?id=24451 ^ permalink raw reply [flat|nested] 5+ messages in thread
