<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">After a blond transfer to a destination that then hangs up, the Local;1 channel would suffer a reference leak. This was due to blond_nonfinal_enter() resetting the props->transfer_target to NULL as it unref'd the channel for itself, later preventing the attended_transfer_properties_destructor() from releasing it's own reference, which was inherited during ast_bridge_impart with INDEPDENDENT.
This change prevents props->transfer_target from being set to NULL, and thus eliminates the leak.</pre>
