My code calls IMG_ReadXPMFromArray(char **xpm) to create an SDL_Surface from an XPM array in memory. That function calls load_xpm(xpm, NULL). That NULL is the 'src' argument, of type SDL_RWops. The first thing that load_xpm() does with 'src' is to call SDL_RWtell(src). SDL/SDL_rwops.h defines SDL_RWtell(ctx) as (ctx)->seek(ctx, 0, RW_SEEK_CUR). Since 'ctx' is null, the process crashes. This all happens in IMG_xpm.c.
This happens with SDL_image 1.2.5. Version 1.2.4 had a different implementation for load_xpm(): it called get_next_line(xpmlines, src, 0) instead of SDL_RWtell(src). get_next_line() did not use 'src' if 'xpmlines' was non-null.

Patch fixing several segfaults
I have got a patch for the same problem in Debian. Applications that worked with SDL_Image 1.2.4 segfaulted a lot with SDL_Image 1.2.5. The attached patch fixes this. I already use this patch in Debian and it looks okay.
