Is this still happening? rev 11157 might have fixed it.

Nothing changed, I'm using my own build of Revision: 10945
 from Dec 16th 2017 . The bug is semi-random in that the particular sequence of mouse movements that I demonstrated in the attached video file to trigger the crash

What changed between comments #6 and #8? Are you using your own build?

reopening and removing guile-1-6 in title.

it still crashes even using guile-1.8, same place as last time
, in Qt

Guile-1.8 is not maintained; this is why Debian does not package it any longer. That's why we need to build it ourselves now. Glad it worked with these debs, and closing the bug since it seems solved.

ALso changing the title from

 

Segmentation fault in QMenu::popup in Linux with QT4 and libguile.so.12

to

Segmentation fault in QMenu::popup in Linux with QT4 and guile-1.6

so that it is clear its related to guile-1.6

great, thanks! It appears to be working quite well. There are no guile-1.8 debs in Ubuntu it seems.. wonder why?

From you last comment, it seems you are running texmacs with guile 1.6. Since we normally run it with guile 1.8, it could be the origin of your issue. I've made guile-1.8 debs for 17.10 (https://download.opensuse.org/repositories/home:/slowphil:/texmacs-devel/xUbuntu_17.10/amd64/), maybe you can try to build with them.

I built the debs from source and uploaded them at https://github.com/crowlogic/stuff/tree/master ... can you try those somehow and see if it still works, maybe using alien to convert to whatever format mint uses, ive never used that one before ? That would perhaps help rule out texmacs vs some library it depends on

I cannot reproduce that in Mint 18. Try renaming your ~/.TeXmacs directory to see if that changes anything. If that does not help, what distribution do you use?

The file uploader is broke, so I put the video of how to reproduce the bug at the URL https://github.com/crowlogic/stuff/raw/master/TexMacsCrash.mp4

To trigger the bug, just start TeXmacs    and then scroll around through the menus.. video attached
