--- Comment #50 from Jürgen Reuter <juergen.reuter at desy dot de> --- How to proceed here? Since almost exactly a month the current gcc git master doesn't show this problem anymore, from our CI I can deduce that the version on July 3rd still failed, while the version on July 10th worked again. Since then the problem didn't show up again. My guess is that something has changed in the optimizer again (maybe because of a different problem/regression). Is it worth to find the offending commit and see when and how it was fixed (maybe even accidentally), or shall we add a gcc testsuite for regression testing, and close this issue?
