Bug ID: 97422
Summary: gcc rejects 'std::initializer_list' when instantiating
with a list
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: tangyixuan at mail dot dlut.edu.cn
Target Milestone: ---
Hi, when instantiating a function with a list of integer type, gcc rejects it
and reports two duplicate error messages. Clang accepts.
$ cat s.cpp
#include <initializer_list>
void func( std::initializer_list<int[1]> list) {}
int main()
{
func( {{1},{2},{3}} );
}
$ g++ -c s.cpp
s.cpp: In function ‘int main()’:
s.cpp:6:24: error: array must be initialized with a brace-enclosed initializer
6 | func( {{1},{2},{3}} );
| ^
s.cpp:6:24: error: array must be initialized with a brace-enclosed initializer
s.cpp:6:24: error: array must be initialized with a brace-enclosed initializer
