is CRITICAL supported in 12.0 or 12.1?

[AShte]

I cannot update from 12.0 and 12.1.

I have a coarray program that uses CRITICAL.

I get:

ifort -c -coarray -free -fPIC -warn all  cgca_m2stat.f90
cgca_m2stat.f90(107): remark #7712: This variable has not been used.   [CG_$1_mtx]
critical
^

At runtime the program seems to hang at CRITICAL, but not always. With 8 or 27 images it seems to work, and with 64 images it hangs.

Please advise

Thanks

It is supposed to be supported. Can you provide a small test program that demonstrates that unused diagnostic? I'd like to track that down, though it should not impact the code. A program that demonstrates the hang would also be useful. Coarray support improved in 13.0.

Sorry, just to clarify, the small program above does *not* hang.

This is just to show the compiler diagnostics.

I'm working on reducing the size of the hanging code.

Thanks - I can reproduce the diagnostic.

The diagnostic issue has been fixed for a release later this year.
