Bug ID: 108047
Summary: ice: unexpected expression of kind implicit_conv_expr
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: dcb314 at hotmail dot com
Target Milestone: ---
For this C++ source code:
namespace std {
template <class> class initializer_list;
struct Trans_NS___cxx11_basic_string;
struct vector {
vector(initializer_list<Trans_NS___cxx11_basic_string>);
};
struct Trans_NS___cxx11_basic_string {
Trans_NS___cxx11_basic_string(const char *);
};
} // namespace std
constexpr auto kBufVecX = "";
template <typename> struct TestXswap {
std::vector BuffersIn() { return {kBufVecX}; }
};
does this
