Maybe packages that have not reached the archtitectures, that showed the test failures on buildd.Thanks for the quick reply! I do wonder whether there's more to it than that, though, particularly in light of the similar if not identical errors libqtdbusmock proceeded to hit on mips (which I reported as #879942 just after you sent your reply). More specifically, this looks like the sort of error that could arise after prematurely freeing memory. Have you tried running under Valgrind, or locally building with -fsanitize=address?
I did build with -fsanitize=address... Output of the unit tests (that don't fail locally here) below.
I really need a way to reproduce the test failures on my local setup (sbuild).
