When I try to inspect std::string variable using LLDB, I get "error: summary string parsing error".
#include <iostream>
#include <string>
int main() {
std::string a{"123"};
std::cout << a << std::endl;
return 0;
}
Process 4492 stopped

4 int main() {
5 std::string a{"123"};
-> 6 std::cout << a << std::endl;
7 return 0;
8 }
(lldb) v a
(std::string) a = error: summary string parsing error

Recompile your source code with the -fstandalone-debug
flag. This option disables optimizations that (may) prevent clang
from emitting type definitions, preventing lldb
from accessing the underlying structure of your environment's std::string
implementation.
