Builds on top of #157, thanks @WyriHaximus for the original version and helping tracking this down with @CharlotteDunois. This changeset builds on top of this, but instead of skipping affected tests will make sure tests pass by clearing any garbage references twice before running any of the affected assertions.
I still wonder if this could potentially be an upstream bug in
ext-xdebug
or PHP itself, but I don't see any guarantees thatgc_collect_cycles()
collects all cycles, so perhaps we were just lucky in previous versions. I consider this minimal changeset to be good enough until we find a better solution in the future
