Sporadic Crash on exit during callq in QObject::disconnect
Sorry I can't be more helpful. This is similar to #99606: sporadic CRASH on exit in QNetworkConfigurationManagerPrivate::pollEngines() on unixes (corrupt stack?) in that it occurs on exit, so is not a serious issue, but still a segfault is a segfault. It will be difficult to know what is going on because is sporadic and because I'm only getting disassembler for the qt portion of the code. Note I'm running Arch Linux x86-64 Qt 5.6 inside QtCreator in debug mode, currently latest master a65f06b
1 QObject::disconnect(QObject const *, const char *, QObject const *, const char *) 0x7fffef488ab7 2 ?? 0x7fffe011bf78 3 ?? 0x7fffe010cb36 4 ?? 0x7fffef284de8 5 start_thread 0x7ffff480e424 6 clone 0x7fffee988cbd
Current dissabemly line of failure is line 130 of QObject:;disconnect:
0x7fffef488ab7 <+0x0277> ff 10 callq *(%rax)
Last time this happened, yesterday, I believe, was same line and similar value of rax.
