Debug build for Mac to produce a useful coredump?

dottedmag · March 11, 2023, 4:56pm

Hello.

I see a quite persistent crash in Anki under Mac (the crash is a null pointer dereference somewhere inside QtGui).

I’d like to get a coredump to prepare a detailed bug report, however I think a crashdump from a release version will be quite useless. Is there a version of Anki built with debug symbols that can be used to create a useful coredump?

Before you can report it to Qt, you’ll need to determine if it can be reproduced outside of Anki and PyQt. When is the crash happening?

It actually looks like a Qt API misuse (something about calling a callback of a destroyed text entry object)

Once I have the crash again I’ll attach the crashdump from Mac (it’s got stacktraces), so we can see if it’s Qt or Anki.

I’ve got the crash again:

Not very convenient formatting, but I’m apparently unable to paste links in this forum :-/

Maybe a smarter person than I might be able to gleen something useful out of that stacktrace, but I’m afraid it’s not telling me much other than that the crash is happening in Qt. Whether this is a Qt bug, or API misuse (eg caused by Python garbage collection deallocating an object early) is not clear at this point, and experimentation will be required to get to the bottom of it. If you can reliably trigger the bug, a good place to start would be to make experimental changes to the Anki code such as disabling garbage collection, and see if the problem persists. When is the crash happening?

dottedmag · March 19, 2023, 6:20am

It happens for me quite reliably. The sequence of actions (not necessarily minimal sequence, but this one triggers the bug 100%):

“browse”
select a card
“create copy”
change the text
change the deck
“add”
“close”

At “close” Anki crashes.

I’ll play around and see what’s going on.

My guess is it’s connected to the gc triggered by self.mw.deferred_delete_and_garbage_collect(self) in the close routine. You may be able to work around it by calling .deleteLater() on one or more of the widgets inside the window after .close() is called.
