On Windows, "negative" exit codes are probably NTSTATUS values. For example, if a program accesses an invalid memory location, Unix sends a SIGSEGV signal which, if unhandled, will terminate the process (setting some kind of non-zero exit code - for example, Linux sets the exit code to 128 + signal number to give a fairly memorable 139). In the equivalent scenario, Windows throws an EXCEPTION_ACCESS_VIOLATION which, if handled by the default exception handler, will terminate the process with exit code STATUS_ACCESS_VIOLATION. These codes are large negative numbers, which are not terribly memorable in decimal, so for negative exit codes we instead display them in hexadecimal as 0xc0000005 is slightly more memorable than -1073741819.
