Bug ID: 106290
Summary: A non-static data member of an anonymous union member
appears in the default-member-initializer of another
should be well-formed
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: xmh970252187 at gmail dot com
Target Milestone: ---
struct B{
union{
int a;
int b = (a,10);
};
};
For this case https://godbolt.org/z/5KnK8azEM, GCC renders an error, with a
diagnosis:
"error: invalid use of non-static data member 'B::<unnamed union>::a'"
However, such use should be valid and does not violate any rule in the
standard. Clang accepts this example.
