Summary:                    [patch] Asterisk crashes after "core stop
gracefully"
Description: 
I have tried to compile and install Asterisk SVN on a fresh copy of Debian
stable. This system has 254728k of RAM and 746980k of swap (is this enough
to compile Asterisk? Are there any error messages, if the system runs into
memory problems?). Compilation process seems to run smoothly.

If I start asterisk and then try to quit it using "core stop gracefully",
there is a segmentation fault.

gdb info is attached.

Fix various problems detected with Valgrind.
 * chan_console accessed pvts after deallocation.
 * cdr_mysql stored a pointer that was freed by realloc()
 * The module loader did not check usecount on shutdown, which led to
chan_iax2
 reading a timer that was already unloaded.
 * The event subsystem sometimes creates an event with no IEs.  Due to a
corner
 condition, the code would read beyond the memory boundary.
 * res_pktccops did not correctly check whether its monitor thread was
started.
