Issue with faulty line coverage

[bolmstedt]

Hi, I noticed something strange when running PHPUnit in a new repository, I got reports that tests were risky because they executed methods that they in reality didn't, because of me using beStrictAboutCoversAnnotation.

When I ran it multiple times, it displayed different methods not being covered by @covers annotations as a result of PHPUnit triggering the tests that were reported risky first.

I think the issue might be with the clear method, but that's just a wild guess after looking at the PHPUnit coverage driver for PCOV.

A minimal repository recreating my issue can be found here.

That's a really horrible bug ... thanks for the report ...

The notification for this was lost among a sea of emails, until 20 minutes ago (I just happened to notice this on github somehow) ... sorry about the delay ...
