Debug symbols don’t inhibit identical code folding. What you get is one copy of the function and one arbitrary file/line entry which makes it look like your program makes impossible function calls, if you happen to walk the stack. This can easily be seen in a C++ program with lots of Protocol Buffers because protobuf generated code has lots of identical small functions.
