I tested the executable on Windows 10 and on Wine, with same result. Maybe your setup is hiding the output? Or the executable is not being started at all? (I've seen that on some environments where a required dll was missing or was incorrect.) I uploaded new excep.cpp/excep.exe files. Now the executable should give signs of life before crashing: $ ./excep.exe Throwing... terminate called after throwing an instance of 'int' terminate called recursively abnormal program termination I suggest to try the reproducer under a normal Windows shell, not some MSYS2/Cygwin terminal emulator.
