I used Thomas's "sync all" code as an example (see https://gcc.gnu.org/

So, although it didn't "hang" it certainly had a few hickup's and 20
seconds elapsed time is rather pathetic for this simple code.
Today I used Thomas's "locks" example code from the same e-mail message
(showing the full output):
$ ~/compilers/install/gfortran-test/bin/gfortran -fcoarray=lib locks.f90
-L ~/compilers/install/gfortran-test/lib64 -lcaf_shmem

As you see, for none of the attempts its results matched the expected
number. It also didn't hang and completed in a reasonable time.
Kind regards,
