/**********************************************************************
* once generated the loop body, verify whether some statement caused
* the analyzer to fail during the 2nd iteration of the loop body (in
* most case, a null/dead pointer dereference would do it), if so, delete
* the statement in which analyzer fails and all subsequent statemets
*
* also performs effect analysis
