Summary:                    ast_channel_set_caller_event reads from a free()'d
pointer
Description: 
In ast_channel_set_caller_event in channel.c there is a check to see if the
callerid has changed. A copy of chan->caller is made and a deep char*
member inside is free()'d.  The old pointer is used in a comparison and
results in a read of memory that has been freed.
