It compiles also with 7.3 and 8.2. At run time I get

At line 341 of file pr87337.f90
Fortran runtime error: Attempt to DEALLOCATE unallocated 'f'

if the code is complied with -fcoarray=lib -lcaf_single. If I add -fcheck=all,
I get

At line 341 of file pr87337.f90
Fortran runtime error: Index '127' of dimension 1 of array 'f' above upper
bound of 126
