Bug description: segmentation fault during request shutdown
Description:
------------
There is an incorrect session destructor registration. The pointer
registered by zend_list_insert points to a memory block which is then
released by efree. This can lead to segmentation fault when destructor is
called. A proposed patch follows (the same problem is id development
branch)
