When initialized, the index of the ElementRegion was unsigned. But the index
value of the ArraySubscriptExpr is signed. This inconsistency caused the value
of the array element retrieved to be UnknownVal despite it was initialized to
symbolic.

This is only a hack. Real fix of this problem is required.
