From: "denis.campredon at gmail dot com" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug c++/108093] New: Quadratic error lines printed with missing include for template Date: Wed, 14 Dec 2022 08:53:35 +0000 [thread overview] Message-ID: <bug-108093-4@http.gcc.gnu.org/bugzilla/> (raw) https://gcc.gnu.org/bugzilla/show_bug.cgi?id=108093 Bug ID: 108093 Summary: Quadratic error lines printed with missing include for template Product: gcc Version: 12.2.1 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ Assignee: unassigned at gcc dot gnu.org Reporter: denis.campredon at gmail dot com Target Milestone: --- Compiled with -std=c++20, who has only missing includes, the following code prints way too much lines of error. Adding or removing one template level drastically changes the number or error lines. ------------------------------------ using namespace std; vector<vector<vector<string>>> foo; ------------------------------------ with std=c++17 only one line is printed : 'vector' does not name a type Ideally, both invocations should print 1 error per unknown type and add fix-hints for the missing includes.
