Bug ID: 125267
Summary: [16.1 regression] segmentation fault in compiled
binary
Product: gcc
Version: 16.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: juergen.reuter at desy dot de
Target Milestone: ---
Hi, we observe segmentation faults in our binaries when built with gcc/gfortran
16.1. For the moment, we cannot provide a smaller reproducer, just to build our
code Whizard (3.1.8) [or alternatively from the public gitlab,
https://gitlab.tp.nt.uni-siegen.de/whizard/public, build it with gcc/gfortran
16.1 and run a simple example (you need OCaml unfortunately). This results e.g.
in the segmentation fault:
