The call to "gdip_find_encoder_parameter (params, &GdipEncoderQuality);" in
jpegcodec.c doesn't find the quality parameter (the GUID don't match). So the
problem lies in the encoding of the parameter and hence in
EncoderParameters.ToNativePtr()/EncoderParameter.ToNativePtr()*. Something in
there must be assuming that we're running on a 32bit system.
