--- Comment #21 from RJVB <rjvber...@gmail.com> --- I have nothing against your initial explicit cast to a QObject*, what about you Yichao? I do think this has to be reported to GCC though. I think the vptr warning is more a bad-semantics-practice warning than one about something that could cause a crash like you're seeing. Although: I don't know about C-style casting to a different class, but casting to a *non packed* struct might let you run into issues caused by different alignment. And *that* could explain the jump into the unknown. Anyway, bug or feature, in the end this is probably something that only people intimately familiar with GCC's internals might be able to explain. -- You are receiving this mail because: You are watching all bug changes.
