Bug report: nvc++ crashes with an invalid openmp collapse

Accelerated Computing HPC Compilers nvc, nvc++ and nvfortran

Hi,

nvc++ (25.1) aborts with a signal 11 on an invalid openmp source code

The execution line is :

 /opt/nvidia/hpc_sdk/Linux_x86_64/25.1/compilers/bin/nvc++  -mp=gpu -O3 essai.cpp -o essai

aborts with the message:

nvc++-Fatal-/opt/nvidia/hpc_sdk/Linux_x86_64/25.1/compilers/bin/tools/nvcpfe TERMINATED by signal 11

My following code should not contain the “collapse(2)”

#include <cstdio>
#include <algorithm>

int main(void)
{
  int n = 3;
#pragma omp target teams distribute parallel for simd collapse(2)
  for (int i = 0; i < 20000; i++)
    for (int k = 0; k < std::min(i, n); k++)
    {
    }
  return 0;
}

It will be fine to report the line of the error.

Thanks for the report!

I’ve filed it as TPR #37158 and sent it to engineering for investigation.
