[Bug c++/85991] [Concepts] Template placeholder: ICE cp_parser_lookup_name, at cp/parser.c:26223
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=85991 Andrew Pinski changed: What|Removed |Added Status|UNCONFIRMED |RESOLVED Target Milestone|--- |9.0 Resolution|--- |FIXED --- Comment #2 from Andrew Pinski --- (In reply to Jonathan Wakely from comment #1) > No ICE with current trunk: Using -std=c++17 -fconcepts (as the syntax for concepts slightly changed): :3:10: error: 'TmplC' does not constrain a type 3 | void f(A> *); | ^~~ :1:56: note: concept defined here 1 | template class, int> concept bool TmplC = true; |^ :3:10: error: wrong number of template arguments (1, should be 2) 3 | void f(A> *); | ^~~ :1:56: note: provided for 'template class, int > concept const bool TmplC< , >' 1 | template class, int> concept bool TmplC = true; |^ :3:10: error: wrong number of template arguments (1, should be 2) 3 | void f(A> *); | ^~~ :1:56: note: provided for 'template class, int > concept const bool TmplC< , >' 1 | template class, int> concept bool TmplC = true; |^ :3:17: error: template argument 1 is invalid 3 | void f(A> *); | ^~ Compiler returned: 1 So I think we can close this as fixed. I could not reproduce the ICE in released version of GCC 9.1 either.
