Bug ID: 100640
Summary: GCC permits explicit instantiation of a constructor
template with an explicit template argument list
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: richard-gccbugzilla at metafoo dot co.uk
Target Milestone: ---
Example:
struct A {
template<typename T> A() {}
};
template A::A<int>();
GCC accepts this without even a warning under -std=c++20 -pedantic-errors, but
this is not valid C++.
If this is an intentional extension, it doesn't appear to be documented (and
presumably should be rejected under -pedantic-errors).
