Bug ID: 110691
Summary: Segmentation fault on valid F2018 code
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: juergen.reuter at desy dot de
Target Milestone: ---
Created attachment 55557

Reproducer
The attached code (which I believe to be valid F2018) leads to a segmentation
violation with gfortran at least since version 11. (it also seg faults,
probably with a different root case) in Intel oneAPI 21.9 (2023 v1), but works
with nagfor.
This is the backtrace of the segfault:
Program received signal SIGSEGV, Segmentation fault.
