Bug ID: 101894
Summary: [11/12 Regression] [concepts] ICE with multiple friend
declarations
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Keywords: ice-on-valid-code
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: reichelt at gcc dot gnu.org
Target Milestone: ---
The following valid code snippet (compiled with "-fconcepts")
triggers an ICE since GCC 11:
=================================
struct A
{
friend void foo(auto);
friend void foo(auto) {}
};
=================================
bug.cc:4:25: internal compiler error: in push_template_decl, at cp/pt.c:5714
4 | friend void foo(auto) {}
| ^

Actually the same ICE happens with regular templates (without the "-fconcepts")
flag:
=========================================
struct A
{
template<int> friend void foo();
template<int> friend void foo() {}

Though that is only on the trunk while the auto one is on the 11 branch too.

Both testcases trigger the ICE for me on the 11 branch (and trunk).

c++: repeated friend template [PR101894]
Since olddecl isn't a definition, it doesn't get DECL_FRIEND_CONTEXT, so we
need to copy it from newdecl when we merge the declarations.
