fix: remove pointer to loop variable when searching the latest event to analyze (#328)

Browse Source 
Having a pointer to a range variable will always yield the latest value
the loop sees. This leads to subtle bugs. To prevent this from
happening, the range variable was assigned to a temp variable, which is
then referenced as a pointer.
