Description Sylvain 2013-06-20 12:34:10 UTC 
I have a crash with latest SDL 2.0 trunk (2013/06/21).

1/ Load an Image XPM with IMG_ReadXPMFromArray()
2/ Try to set a ColorKey on it.

I notice that : 
- the SDL_Surface that is created from XPM has a palette !
- the colorkey is a RBG.

it crashes (SIGSEGV) inside the SDL_SetColorKey function:
"surface->format->palette->colors[surface->map->info.colorkey].a"

Thanks for the report.  Can you attach a small program that crashes?

small program that crashes

Here's a small program that crashes, needs SDL2 + SDL2_image

It crashes because I try to set as a colorkey, a RGB color which gets out of the bounds of the palette of the image.
