Test source: https://github.com/fujitsu/compiler-test-suite/blob/ac5d63a278b47141b51e12bd7ec3b189177d63e9/Fortran/1054/1054_0035.f90

Similar test: https://github.com/fujitsu/compiler-test-suite/blob/ac5d63a278b47141b51e12bd7ec3b189177d63e9/Fortran/1054/1054_0026.f90

Result:

$ flang -fopenmp 1054_0035.f90 && ./a.out
flang-21: warning: OpenMP support in flang is still experimental [-Wexperimental-option]
 NG : xpno(1)= 4
 NG : xpno(2)= 11
 pass

The NG lines should not be printed for the test to pass. (pass should be the only output for the passing test.)

flang version:

flang version 21.0.0git (https://github.com/llvm/llvm-project b1017a4b84420894c0aedfe3872ef617f66f087f)
Target: x86_64-unknown-linux-gnu
Thread model: posix
InstalledDir: ...
Build config: +assertions

I don't see anything obviously wrong with the test, but I hope OpenMP experts could investigate it further.
