codecServer Buffer error

From the trace logs, it looks like the codec is returning pointers to buffers that are not accessible from the ARM side.  Notice from the error msgs on the ARM side that the addrs in question (e.g. 0x85d343a5) are coming from the CODEC SERVER memory section (0x85900000+), not the CMEM memory (0x83700000 - 0x858fffff).  The codec should not be returning pointers to memory that the [ARM-side, in this case] application didn't give it.

I've moved this to the Codec Forum.  Can you provide details about which codec this is, including the version?
