Random SIGTRAPs in DecommitSystemPages on Arch Linux

Steps to reproduce

I’m not really sure what causes this, but the element desktop client isn’t very stable. Sometimes, when switching between rooms via alt+up/alt+down, it crashes without any warning or anything; other times, like just now, it crashed, again, even though I wasn’t doing anything other than chatting, and when I tried reopening it in the console after it crashed several times in sequence it said “Trace/breakpoint trap (core dumped)”. I can’t seem to find said core dump, nor can I seem to find the cause. I wish I could provide more info (maybe there’s a way to do it and I just don’t know).

Outcome

What did you expect?

I expected Element to start correctly.

What happened instead?

Element crashed several times, and tends to crash at random.

The output in the console before it crashed follows:

Operating system

Arch Linux

Application version

Element version: 1.10.1, Olm version: 3.2.8

How did you install the app?

I installed the app from the Arch Linux repositories via pacman.

Homeserver

I’m using synapse 1.51

Will you send logs?

No

[MountainX]

I get these SIGTRAPs whenever I have the search indexing enabled. I can very reliably trigger a crash whenever I do a fresh login and it has to rebuild the search index.

Yes, the same for me on Arch Linux.

Yeeep, disabling the encrypted search index stopped the crashes for me. Not a favorable long-term workaround, though
