            Bug ID: 110720
           Summary: Internal compiler error (segmentation fault) in
                    gfc_expression_rank
           Product: gcc
           Version: 13.1.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
          Assignee: unassigned at gcc dot gnu.org
          Reporter: adrien.morison at gmail dot com
  Target Milestone: ---

Created attachment 55569
  --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=55569&action=edit
Minimal test case triggering the problem, foo_mod.f90 in the above command

This is with a development snapshot on commit
bef95ba085b0ae9bf3eb79a8eed685236d773116

Compiling the attached code lead to an internal compiler error. The attached
code is a self-contained example that triggers the problem, and is a stripped
down version of the actual code (which does a bunch of computations instead of
setting things to 0).

Command:
gfortran -v -save-temps -freport-bug -c foo_mod.f90

Output:
Using built-in specs.
