Comment on the line 504 causese segmantation fault
A segmentation fault occurs in case there is a comment at the end of a data
block with a large number of elements (>496).
This happens in flang-7(supplied by Debian buster), flang-10 (Aocc2.2), and
flang-11 (Aocc2.3).
gfortran8.3 and ifort2021.1 can compile this attached file by
"gfortran -c test.f", and "ifort -c test.f" respectively.
My PC's output of "uname -a" is
Linux mypc 5.10.0-0.bpo.3-amd64 #1 SMP Debian 5.10.13-1~bpo10+1 (2021-02-11)
