Bug ID: 107574
Summary: [10/11/12/13 Regression] ICE: tree check: expected
record_type or union_type or qual_union_type, have
integer_type in cp_fold_convert, at cp/cvt.cc:613
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: gs...@t-online.de
Target Milestone: ---
Affects versions down to r9 :
$ cat z1.cc
struct A { int i; };
struct B:A { int j; };
struct C:B { int k; static_assert((int(B::*))&C::k, ""); };
$ g++-13-20221106 -c z1.cc
