Bug ID: 98352
Summary: [9/10/11 Regression] ICE in implicitly_declare_fn, at
cp/method.c:2914
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: gscfq@t-online.de
Target Milestone: ---
Changed between 20190217 and 20190224, and affects roughly
a dozen testsuite files when running without -std=c++11 :
$ cat z1_nsdmi-defer6.C
struct A
{
int i = (A(), 42);
};
A a;
$ g++-11-20201213 -c z1_nsdmi-defer6.C -ansi
z1_nsdmi-defer6.C:3:19: warning: non-static data member initializers only
available with '-std=c++11' or '-std=gnu++11'
3 | int i = (A(), 42);
