I tested a similar GHCi session as the ones above with a Bitmap file I found in the wild and I encountered the same results for Bitmap Word8, Bitmap Word16 and other exceptions for Bitmap Word32, Bitmap Float.
> readBitmap "chef.bmp" :: IO (Bitmap Word32) > *** Exception: mallocForeignPtrBytes: size must be >= 0 However, there is still the possibility that this Bitmap might be corrupted either. Just thought I'd report this.
