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.
