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.
