Daniel Wyatt 2010-03-26 14:52:53 PDT If a non-console Windows SDL program has a non-quoted 0th argument followed optionally by more non-quoted arguments and then by an empty quoted argument, it will crash (attempts to dereference a NULL pointer). In other words, something like this: test.exe [non-quoted args] "" [...] The fix is a one-liner in ParseCommandLine() of src/main/win32/SDL_win32_main.c. You can test this with any non-console SDL program on windows like this: 1) Open a console (cmd.exe) 2) Launch the program in one of the following ways: program "" program arg1 "" program arg1 "" arg3 These will not cause a crash: "program" [...] program "arg1" "" When a Windows program is launched from Explorer, its 0th argument seems to always be quoted, so it won't be a problem in that case. I've tested this on Windows XP SP3 and Windows 7.
