View Full Version : Unmap crash with map_read

11-26-2009, 02:57 AM

I experience a crash in clEnqueueUnmapBufferObject if I map a buffer (created with USE_HOST_PTR) with a READ access .

If use READ_WRITE map access or if I use COPY_HSOT_PTR : there is no problem.

Is it a bug (I use nVidia 195.55 under vista 64), or a bad usage of mapping?
