Crash when using OpenACC with gfortran

I am experimenting a bit with OpenACC to accelerate my program, but unfortunately I get a crash at the first directive. The attached program is a minimal reproducer for this problem.

Details:
Windows 11, gfortran version 15.2.0 (I obtained this from equation.com, that may be an important detail).
Compile options: -fopenmp or -fopenmp -foffload disable - the behaviour was the same, a crash.

I also tried this on a Linux system, with version 13.2.0 and that ran fine.

Any clues? I would immediately believe that I am making a trivial mistake somewhere …
