Summary: opreport xml total count differs

Initial Comment:
The total samples collected with opreport and opreport -X differ when using --separate=lib. In particular it seems that the total count displayed by opreport -X is off by exactly the number of samples collected for the last module.

This seems to be slightly related to https://sourceforge.net/tracker/index.php?func=detail&aid=1982201&group_id=16191&atid=116191

Steps to reproduce : (Any simple C program executed multiple times as below should reproduce the issue)
