Texmaker crashes (segmentation fault)

dietzi96 · 2024-12-12 21:34:04

Hi,

when I use texmaker it segfaults when clicked on compile fast. When started by terminal the following is printed:

beginResetModel called on without calling endResetModel first
segmentation fault (core dumped)

After having tried compile fast and a crash, texmaker crashes when loading that .tex file, too. I am using texmaker 6.0.0-1 with sway as desktop environment. Reinstalling texmaker did not help.

Any ideas? Is there an option to show more debug information (-v or --verbose did not work)?

Hey,

I just had the same problem, when run through terminal with the verbose setting i get the same fault

 beginResetModel called on without calling endResetModel first
Segmentation fault (core dumped)

I tried reverting texmaker to an older version and only got the segmentation fault. after playing with it a bit I managed to compile a pdf by switching the method from quick build to PDFLaTeX but can only occasionally get the pdf to display in Texmaker. When i do get the pdf to display it seems fine and stable and I can use any build method I want. seems like it has something to do with displaying the pdf but the behavior is very inconsistent. At the very least this is workable but far from ideal.

As a workaround, you could switch to TeXstudio, a successor to texmaker.

okay so I went and got the core dump, looks like it exited with signal 11 from what I understand that means that it has written into memory that is not allocated for it but I still don't know what to do with this. Attached is the output I got from the core dump.

Crashes inside the texmaker code and is related to PDF bookmarks when opening the PDF?
Does this happen w/ every tex file? Anything special about yours? Tried some demo file?

https://fossies.org/dox/texmaker-6.0.0/ … tml#l00159
Since BookmarkNode::clear operates on a QVector, it's more likely that m_rootNode is dangling at this point.
I couldn't find any kind of bugtracker for texmaker, apparently you can send a message via https://www.xm1math.net/texmaker/doc.html#contact :\
