Dvoid from Discord just reported a crash when trying to load a custom tiles2.png that was encoded weirdly. The problem is that we don't check the return value from LodePNG, so LodePNG gives us a null pointer, and then SDL_CreateRGBSurfaceFrom doesn't check this null pointer, which then propagates until we crash in SDL_ConvertSurfaceFormat (or rather, one of its sub-functions), and we would probably crash somewhere else anyway if it continued. After properly checking LodePNG's return value, along with printing the error, it turns out that Dvoid's custom tiles2.png had an "invalid CRC". I don't know what this means but it sounds worrying. `feh` can read the file correctly but it also reports a "CRC error". |
