Hello everyone :)
I am a new boost user, and I'm trying to convert a large project to use
smart pointers. I have a use for shared_array buy the memcpy line from

following code snippet(, and all memcpy's) throw an exception with the shared_arrays and I don't know why. Am I doing something obvious wrong?
Do you ever do a r_packet.reset( new uint8[data_length] )? Put a debugger breakpoint at entry to c_Packet, and see if r_packet has been reset. HTH, --Beman
Thank you, Blake
