Reduced reproducer

I git a bug in gcc 13.2 where an openmp loop causes he compiler to spin the
cpu, and never finish. I used creduce to minimize the test case, and the
reduced source is attached.

I'm running Debian GNU/Linux with gcc=4:13.2.0-1. I get an infinite loop with

  gcc-13 -fopenmp -c -o /dev/null /tmp/infinite-openmp.c

I happen to also have gcc-10 and gcc-11 installed, and they both produce an
infinite loop with that input as well.

Thanks
