Sorry, I attempted to bisect this, but ran into LLVM build issues during the bisection that I couldn't get past. Perhaps bisect landed on a patch that just happened to have LLVM build issue, but I wasn't able to get past it.
The failures started around 4-Jun-2025 and both tests started failing with the same build. This LLVM commit is known to work: 54d836a
The first test outputs err line, which should not be in the successful output:
$ flang -fopenmp 0521_0030.f90 && ./a.out
flang-21: warning: OpenMP support in flang is still experimental [-Wexperimental-option]
err var i1= 1
pass
The second test currently hangs:
$ flang -fopenmp 0686_0024.f90 && ./a.out
flang-21: warning: OpenMP support in flang is still experimental [-Wexperimental-option]
^C
At some point I saw it failing as follows:
10011 10011 10011 0
10011 10011 10011 0
pass
(Only pass should be printed upon successful output.)
