Segmentation fault when running as non-root on Arch Linux

[eskalVAR]

I have compiled the package using the user provided : https://aur.archlinux.org/packages/notekit-clatexmath-git

clatexmath-git dependency is met by : https://aur.archlinux.org/packages/clatexmath-git

---

For some reason when I run the package by itself it seg faults:

`== This is notekit, built at Wed Jun 15 22:13:43 2022. ==
Detected paths:
Config: /home/viking/.config/notekit
Active notes path: /home/viking/.local/share/notekit
Default notes path: /home/viking/.local/share/notekit
Resource path: /usr/share/notekit

Segmentation fault (core dumped)

Running as sudo is fine :

== This is notekit, built at Wed Jun 15 22:13:43 2022. ==
Detected paths:
Config: /root/.config/notekit
Active notes path: /root/.local/share/notekit

I know exactly what the issue is. I accidentally made cLaTeXMath free a statically allocated variable.

This should be addressed by NanoMichael/MicroTeX#86 . Alternatively you should also be able to unset XDG_DATA_HOME, then it should work too.

Yes this does work! Wish I didn't have but it's an okay temporary fix.

Weird that the PR you linked hasn't been pulled in. I have yet to try that solution.

Thank you!

FWIW, can confirm that unsetting XDG_DATA_HOME works.

That's a weird one.

For someone looking for a configuration-side easy fix, copy /usr/share/applications/com.github.blackhole89.notekit.desktop to $XDG_DATA_HOME/applications (SCNR — it's ~/.local/share/applications) and modify the Exec directive to read something like

Exec=env -u XDG_DATA_HOME notekit
