Bug ID: 91120
Summary: broken template instantiation for std::string_view
values
Product: gcc
Version: 9.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: development at jordi dot vilar.cat
Target Milestone: ---
The following code fails to compile with gcc 9.1 and -std=c++2a:
#include <string_view>
using namespace std::string_view_literals;
template<std::string_view> struct test_type {};
auto test = test_type<""sv>{};
reporting the following diagnostics message:
error: '""' is not a valid template argument of type 'const char*' because '""'
is not a variable
using other literal types (integral types, std::array, etc.) seems to work.
