Ticket Resolution Summary Owner Reporter
#1252 fixed OSX udp socket, "Socket is already connected (error #56) during sendto" R. Matthew Emerson Josh Kordani
Description

on osx 10.7.5.

when attempting to call send-to on a socket that already has remote-port/host or local-port set, ccl reports "socket is already connected (error #56) during send-to"

code example to tickle this problem http://paste.lisp.org/display/144678

after evaluating the defparameters calls to create the test vector and the socket, all three of the send-to calls fail with the same problem

Similar problems are encountered in python apparently. see https://github.com/zerovm/zerocloud/issues/86

#1262 fixed Invalid memory operation from %copy-ivector-to-ivector-predecrement-128bit R. Matthew Emerson Bill St. Clair
Description

I'm converting WOOD to run in CCL. It uses ccl::%copy-ivector-to-ivector to quickly copy (unsigned-byte 8) arrays. While stressing its btree code, I encountered an "Invalid memory operation" error in ccl::%copy-ivector-to-ivector-predecrement-128bit

The errors happens in 64-bit CCL 1.10 on both my iMac and my Windows laptop running Ubuntu 14.10.

Executing (copy-ivector-to-ivector-bug) from the attached file makes it happen. The GDB output at the bottom of the file is from my Windows laptop running Ubuntu 14.10.
