[Bug] - Crash at mailcore::IMAPOperationQueueCallback::queueStartRunning() #1888

Open 2h4u opened 4 years ago

2h4u commented 4 years ago

Summary I am experiencing some crashes with the following stack trace:

In my opinion it looks like that at https://github.com/MailCore/mailcore2/blob/0.6.4/src/async/imap/MCIMAPAsyncConnection.cpp#L59 the pointer of mConnection is not valid anymore (for whatever reason) but of course I could be wrong.

Any ideas how tho fix this issue?
