Bug ID: 118078
Summary: [12/13/14/15 Regression] GCC crashes on incorrect code
with -std=c++20 since r10-4719
Product: gcc
Version: 15.0
Status: UNCONFIRMED
Keywords: ice-on-invalid-code
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: jakub at gcc dot gnu.org

Depends on: 116108
Target Milestone: ---
+++ This bug was initially created as a clone of Bug #116108 +++
template <class T>
struct S { struct U { S s; } u; };
S t{2};
(or cv qualified versions thereof somewhere) or say
template <class T>
struct S { struct U { struct V { const struct W { const S s; } w; } v; } u; };
S t{2};
still ICE, looking just at currently_open_class isn't enough, there can be many
open classes at the same time.
All this still started with r10-4719-g9b41ebbcdf9e33285a0eebeb7c841afe20e4a7c1
