Trying to know how qkeyword works I encountered a segmentation error: # gdb --args qkeyword -p dev-util/geany -T GNU gdb (Gentoo 11.2 vanilla) 11.2 Copyright (C) 2022 Free Software Foundation, Inc.

Add two `!= LULL`s if preferred to be pedantic. Obviously some parts of the code might need to be changed too, or perhaps archlist needs to be made sure to be initialized to an array, or maybe simply initialized as "" instead. I didn't study how other parts of the code works. Also as a side note, isn't portage-utils a "Gentoo Hosted Projects"? I don't see it in the selectable components so I'm reporting this in "Gentoo Linux" instead. Maybe allow https://github.com/github/portage-utils to have issues to be reported there too.
*https://github.com/gentoo/portage-utils I like to know why the archlist is empty too. Is it dependent on the package matches? Or is it system config based. If anyone has an idea, kindly tell, thank you.
Please run 'bt' in gdb as well and include its output.

I think qkeyword_load_arches is responsible for filling archlist. It assumes it is set, which is a bit awkward since load_arches can just fail when profiles/arch.list isn't found in the tree in question. Can you try commit 25853d2? Thanks

Fabian Groffen: Looks like it was a problem on my side as well. I wrongly set [gentoo] in a local repo config probably making qkeywords detect "gentoo" as local instead, making no arch.list detected. The suggestion in the message to run `q -o` helped me realize it. Anyway I no longer see segmentation issues and it seems to have fixed it, thanks.
cool, a nice and informative message is always better than segfault :) Thanks for testing!
