--- Comment #4 from Dmitry Babokin <babokin at gmail dot com> --- Richard Sandiford, could you please have a look as author of the commit, which brought the regression? We have a bunch of other fails, which might be or might be not the same as this one. We'd like to avoid spamming developers with duplicates, so waiting for this bug to be fixed. Also, if there's a way how we can help investigating this bug, we would appreciate your guidance.
