[Edward Byard]

Can you post some code for us to look at?

Subject: [SDL] Trying to understand why SDL_GetRGB() crashes

Dear All,

I keep running into situations where SDL_GetRGB() crashes my app (SIGSEGV).
I don't understand why the call would crash; perhaps you can enlighten me
with your ideas. 

Let's assume that all 4 pointer arguments are correct; I've checked this
over and over again.
If the first 'pixel' argument is invalid then I would expect incorrect
results, but no crash.
I use the call on surfaces that I have previously loaded with images from
disk via IMG_Load().
It might have something to do with (BMP) images with indexed colours; it
doesn't seem to happen with 24 bitmaps.

I use:
- SDL-1.2.11
- mingw
- ms vista

Thanks,
Maarten Engels
