Summary: [15 regression] segmentation fault in legacy F77 code
Product: gcc
Version: 15.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: juergen.reuter at desy dot de
Target Milestone: ---
Some changes in gcc/gfortran between ca. June 10 and June 17, 2024 now leeds to
segmenation faults in our application (Whizard v3.1.4, c.f.
http://whizard.hepforge.org/whizard-3.1.4.tar.gz). Note that this appears in
our functional testsuite which necessitates the OCaml compiler. The
segmentation fault appears e.g. as
#0 0x7f827594f51f in ???

I need to come up with a workable reproducer, but that's not easy, and my time
nowadays is awfully limited. :(
