Locals/Watch window displays std::map<enum, struct> incorrectly #12102
Description
Environment
- OS and version: Ubuntu 22.04.3 LTS (WSL2)
- VS Code: 1.87.2
- C/C++ extension: 1.19.8
- GDB / LLDB version: 12.1
Bug Summary and Steps to Reproduce
Bug Summary:
When an std::map is instantiated with an enum class as the key and a struct as a value, the map displays "improperly" in the watch or local window, meaning that the key does not render properly. An std::map<int, struct> or std::map<enum, int> displays as expected.
Steps to reproduce:
Minimum reproducible example:
#include <map>
enum class foo {A, B};
struct bar {
int x = 5;
int y = 6;
};
int main(int argc, char * argv[]) {
std::map<foo, bar> m1;
std::map<foo, int> m2;
std::map<int, bar> m3;
m1[foo::A] = bar();
m1[foo::B] = bar();
m2[foo::A] = 0;
m2[foo::B] = 0;
m3[0] = bar();
return 0;
}
Compile and check view m1, m2, and m3 in watch or local window.
