[Bug c++/107484] [13 Regression] ICE: Segmentation fault (in decls_match)
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=107484 --- Comment #3 from CVS Commits --- The trunk branch has been updated by Jason Merrill : https://gcc.gnu.org/g:0dfbb28a9549c2503204b0338bf550f1bff9c681 commit r13-6992-g0dfbb28a9549c2503204b0338bf550f1bff9c681 Author: Jason Merrill Date: Mon Apr 3 18:23:58 2023 -0400 c++: friend template matching [PR107484] Here friend matching tries to find a matching non-template friend and fails, so we mark the friend as a template specialization to be determined later. Then cplus_decl_attributes tries again to find a matching function and gets confused by DECL_TEMPLATE_INSTANTIATION without DECL_TEMPLATE_INFO. But it doesn't make sense for find_last_decl to be trying to match anything with DECL_USE_TEMPLATE set; those are matched elsewhere. PR c++/107484 gcc/cp/ChangeLog: * decl2.cc (find_last_decl): Return early if DECL_USE_TEMPLATE. gcc/testsuite/ChangeLog: * g++.dg/lookup/friend25.C: New test.

Also crashes with a release checking build:
> ./cc1plus -quiet t.ii
t.ii:5:52: internal compiler error: Segmentation fault
5 | friend void qualified_friend_no_match::f(double);

0x7b6de6 find_last_decl
/home/rguenther/src/trunk/gcc/cp/decl2.cc:1630
since it's not error-recovery it's still P1.
Also crashes with
namespace qualified_friend_no_match {
void f(int);
template void f(T*);
struct X {
friend void qualified_friend_no_match::f(double *);
};
}
which looks more valid to me, but I'm not a C++ expert (but clang++ 13 accepts
it - but that also accepts the original testcase).
