Bug ID: 111222
Summary: ICE on basic_string_view with missing template
argument
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: stevenxia990430 at gmail dot com
Target Milestone: ---
The following invalid program reports an internal compiler error. Failed on
gcc-trunk.
To quickly reproduce: https://gcc.godbolt.org/z/To8EdvdhM
```
#include <string_view>
template <typename T>
using string_view = std::basic_string_view<T>;
string_view my_string = "12345";
```
note after providing the valid declaration (i.e., string_view<char> my_string =
"12345";) the program compiles successfully
