Subjectfew dozen pollfress.t segfaults messages in system log
I got a bunch of

$ grep pollfree messages

last night with kernel 6.4.9 at a stable hardened Gentoo Linux:

Linux p14s 6.1.44 #34 SMP Tue Aug 8 21:43:00 CEST 2023 x86_64 AMD Ryzen
7 PRO 6850U with Radeon Graphics AuthenticAMD GNU/Linux

I do wonder if those messages are related to the host kernel or if they
are coming from a buggy app within one of the images of the build bot I
do run at that machine ?
