Description of the issue
It appears when comparing Location
of two different elements non-existent or incorrect results are found.
Try the query below on the default projects on https://lgtm.com/query:
import java
from ArrayTypeAccess arrayTypeAccess, Location location, RValue other, Location otherLocation
where
arrayTypeAccess.getFile() = other.getFile()
and location = arrayTypeAccess.getLocation()
and otherLocation = other.getLocation()
and location.getStartLine() = otherLocation.getStartLine()
and location.getEndLine() = otherLocation.getEndLine()
and location.getStartColumn() = otherLocation.getStartColumn()
and location.getEndColumn() = otherLocation.getEndColumn()
select arrayTypeAccess, other
It finds ArrayTypeAccess' where there are none and also finds RValues of variables which do not exist at that position.
