Bug ID: 105745
Summary: Conditional OpenMP directive fails with GCC 12
Product: gcc
Version: 12.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libgomp
Assignee: unassigned at gcc dot gnu.org
Reporter: reiter.christoph at gmail dot com
CC: jakub at gcc dot gnu.org
Target Milestone: ---
Downstream issue: https://github.com/msys2/MINGW-packages/issues/11729
The following example crashes with GCC 12.1.0, but works fine with GCC 11.3.0:
// g++ -fopenmp -o broken.exe broken.c; ./broken.exe; echo $?
int main() {
#pragma omp parallel for if (0)
for (int idx = 0; idx < 0; ++idx) { }
return 0;
}
* Removing the "if (0)" condition makes it work again
* Replacing libgomp-1.dll with the one from GCC 11.3 also makes things work
again.
* Another example that crashes is "#pragma omp for schedule(dynamic)"
This is on 32/64 bit Windows.
