Interesting, I guess, but you're using old Qt 5.15.13 (not in tree anymore) and old libktorrent. Update your system and try to reproduce it with libktorrent-24.05.1.
Created attachment 897435 [details] with updated system, in `zip -9` : build.log , testlog , environment, emerge --info, emerge -pqv libktorrent I can reproduce with updated system on version 23.08.5 Let me check with new version.

(In reply to Arniii from comment #3) > iteration 1: IT HAPPENS when just -O0 -pipe -ggdb3 -frecord-gcc-switches Not reproducible here even with 23.08.5. Are you sure about your options? Latest logs still contain -flto.
Please understand that options like LTO may affect libraries hence testing in a clean chroot and doing some work to figure out precisely what causes something is welcome. I am happy to look into exotic issues *once they've been reduced into something reproducible*, but I can't spend time on chasing dragons.
In this particular case, it might well depend on the filesystem PORTAGE_TMPFS resides on. But my advice above applies in general.

(In reply to Sam James from comment #10) > In this particular case, it might well depend on the filesystem > PORTAGE_TMPFS resides on. But my advice above applies in general. After some researching, I've found you were right. It depends on filesystem of /tmp . ext4 - success `PARTUUID=c09c8e8a-0fca-4ee9-b72a-3bebbd3625eb /tmp ext4 defaults,noatime 0 1` tmpfs - success `tmpfs /tmp tmpfs rw,nosuid,nodev,size=4G,mode=1777 0 0` btrfs - success `PARTUUID=c774ac8a-3ccf-441f-b950-238696051d23 /tmp btrfs defaults,noatime 0 1` xfs - fail .

Since you've isolated this to XFS, if it is reproducible 100% also with latest 24.05.2, you can file this bug upstream (on bugs.kde.org) instead.
