Better make that:
vbuf->height = [imageRep pixelsHigh];

The size of an imageRep doesn't necessarily match its pixel dimensions.
Thanks for the tip. Unfortunately I still got the exception as the
vImageScale_ARGB8888 is called. Follows an extraction of the used code.

------------------------------------------------------
src = (vImage_Buffer*)malloc(sizeof(vImage_Buffer));
bpp = [ imageRep bitsPerPixel]/8;
src->height = [imageRep pixelsHigh];
src->width = [imageRep pixelsWide];
src->rowBytes = [imageRep bytesPerRow];
src->data = [imageRep bitmapData];
dest = (vImage_Buffer*)malloc(sizeof(vImage_Buffer));
dest->height = 300;
dest->width = 300;
dest->rowBytes = dest->width * bpp;
dest->data = malloc( dest->rowBytes * dest->height );
vImageScale_ARGB8888(src, dest, NULL, 0);
