56 | 3 | Greg Burri | For some leaks the file and the line are not displayed because the code doesn't contain any debug information, a lot of the leaks shown below come from static variables from the _Protocol Buffer_ library. The leak from @main.cpp:43@ is just a test, this line has been added: @int* test = new int[10];@ |
