An user have a program of ec, function correctly since february,
but of few day ago, don't work more ok , run several minutes and when begin
access of rows (after BIG select with "union") stop and display
Bus Error(coredump) ,She view core with gdb and the last line run not have problem
this program call a function many times. If this code replace (copy and delete
the line) the call, work!!.
