Flang segmentation fault when compiling large data block with comment

Open sohnishi opened this issue 3 years ago • 2 comments

test.f.txt

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) x86_64 GNU/Linux
