--- Comment #2 from Tobias Burnus <burnus at gcc dot gnu.org> --- (In reply to Tobias Burnus from comment #1) > As you could nail it down to a single commit, I assume, you could reproduce > the problem – still, I am completely lost why it fails for you at -O0. Can > you try to debug it a bit more? Was mislead by the time out message. When updating the patch (changing abort to stop), I missed to enumerate the stops through, hence, there is more than one 'stop 1'. Can you pin-point it to a certain stop/fail, e.g. by running it in the debugger? [I will update the test to have disjunct stop numbers.] [Still, as the patch only added 'dg-do run', it still does not explain why it worked before and fails now.]
