Yes, I can, it worked before I upgraded, and it works now I have just downgraded

Got the same openmp issue with this sample:

#include <stdio.h>
int main() {
 #pragma omp parallel for if (false)
 for (int idx = 0; idx < 10; ++idx) { }
 printf("success\n");
 return 0;
}

compiled with: g++ -fopenmp -o myTest.exe myTest.cpp

If I remove the if (false) from openmp statement, then it works.
