hlt2_protoparticles_baseline output is different in dbg builds
The hlt2_protoparticles_baseline
test is failing since May 13 (lhcb-master/1681). The incomplete reference update seems to have been absorbed in the meantime with other reference updates.
However, in today's lhcb-master/1691, the -dbg test fails whereas the -opt test passes. This inconsistency must have started some time ago, and could also be the source of this test having bad reference updates (since forcing in that particular case does not help).
Also, in today's build, and the last one (May 21), the test took 18k seconds in -dbg. In the previous build, it took 10 minutes. This is also true in lhcb-head, so it's probably a real issue.
