twmnd crashes after a random amount of time #89

Open sniff122 opened 4 years ago

sniff122 commented 4 years ago

For a while now i have had twmnd crash, printing the following error when crashing

twmnd: /usr/include/boost/optional/optional.hpp:1217: boost::optional<T>::pointer_type boost::optional<T>::operator->() [with T = QVariant; boost::optional<T>::pointer_type = QVariant*]: Assertion `this->is_initialized()' failed.
Aborted (core dumped)

I have tried to do some googling and stuff what wasnt exactly useful i think, as far as i know boost 1.71 is up to date. I have twmnd start on i3 login with an exec in the config and then i start it in screen when it first initially crashes just so i can hide the terminal with twmnd. I have used twmnd in the past without any forms of crashes and im really not sure on what is going on specifically.

It appears from what I can find is this was addressed in the boost dev branch boost 1.72.0-2 is all I have on hand to check but it has been fixed in that release but I can not find at what release the fix was pushed.

Same problem here, arch linux, twmnd installed from AUR.

This is the relevant part of the output of journalctl -b --user-unit twmnd:

The crash is always at that same location, so this looks like a bug in twmn. I'll try to run a version of twmn built with debug symbols for a while to see whether I can find out the offending line.

I compiled and installed from the github repo, ill try a different version too, I have noticed that it crashes when i have discord's desktop notifications enabled. I havent seen any crashes with it disabled but the only way i notice if twmnd has crashed is by discord freezing up (what is a known issue with discord or electron)
