It was also a bit less efficient than the constructor you get from the compiler by default (which is allowed to just copy the memory). This gives a marginal (~0.25%) decrease in code size when compiled with GCC 9.3.

Using str() means that we create a std::string (strlen; malloc; memcpy), compare for equality (another memcmp if they have the same length) and then finally free the string. Using c_str() means that we pass the const char* straight to std::string's equality operator. This ends up as a call to std::string::compare (the const char* flavour), which is essentially strcmp.
