Bug ID: 118024
Summary: ICE when building openssh-9.9_p1 with -fstrub=all
(internal compiler error: tree check: expected
tree_list, have identifier_node in
matching_alloc_calls_p, at
gimple-ssa-warn-access.cc:1965
Product: gcc
Version: 15.0
Status: UNCONFIRMED
Keywords: ice-checking, ice-on-valid-code
Severity: normal
Priority: P3
Component: middle-end
Assignee: unassigned at gcc dot gnu.org
Reporter: sjames at gcc dot gnu.org

Target Milestone: ---
Created attachment 59856
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=59856&action=edit
vis.i.xz
Doubly concerning, of course, as we have both the ICE and the memory
corruption:
```
$ gcc vis.i -fstrub=all
during GIMPLE pass: waccess
vis.c: In function ‘stravis.strub.0’:
vis.c:217:1: internal compiler error: tree check: expected tree_list, have
identifier_node in matching_alloc_calls_p, at gimple-ssa-warn-access.cc:1983
free(): invalid size
gcc: internal compiler error: Segmentation fault signal terminated program cc1
Please submit a full bug report, with preprocessed source (by using
