It's 2023 and this bug is still present, hilarious but horrendous. Seems I need to brush Objective-C++ and integrate some sane solution like spdlogger, would be better.

XCode contains command line tool called leaks. Use it as follows: compile your_program_to_check with debug information: clang++ -g src.cpp -o your_program_to_check export MallocStackLogging=1 leaks --atExit --list -- ./your_program_to_check Report will hopefully give you lines where leaks occur.

Hi, did you resolved this?
