Attempt to reproduce raboof/notion#345
|
I linked notion to libX11 1.8.1 in raboof/nixpkgs@bb8ba82 but that did not reproduce the problem. Verified it does link to libX11 1.8.1: ... but works normally. Can anyone reproduce this and provide a backtrace? |

Here's the backtrace. I noticed now that it doesn't crash like this every time, but when it doesn't crash it instead hides all windows and doesn't respond to any commands. |

Okay... so apparently it's happening while processing the graphics engine ( This is well after Any ideas? |

Could you perhaps try explicitly calling |

I've now tried calling I rebuilt notion with this patch: --- notion-4.0.2+dfsg.orig/ioncore/ioncore.c

Aha, so that suggests the problem might not have anything to do with https://gitlab.freedesktop.org/xorg/lib/libx11/-/commit/afcdb6fb0045c6186aa83d9298f327a7ec1b2cb9 after all? Definitely 'something with threads and mutexes' though - and still something we'd want to fix, of course.
Thanks a lot, that at least gives us something to go on :). So it's also happening in the graphics engine initialization ( I'm afraid I won't be able to dig much deeper right now, I'm rather busy the coming weeks - would be great if you could hunt it down further! |

I don't think this is a bug in notion. I think the problem is that libX11 uses pthreads but is not built with -pthread. I've written up my findings here: https://gitlab.freedesktop.org/xorg/lib/libx11/-/issues/157#note_1499394 |

Thanks a lot for the analysis. I guess there's nothing we can do from the Notion side - it would be nice if we could detect the problem and warn about it specifically, but even that sounds like it'd be a challenge. Hopefully this issue gets indexed by search engines and provides a good hint for other people running into this problem :) Feel free to re-open when you think of something we could do from the Notion side. |

Rebuilding libx11 with the new
