System: NetBSD unpluged.duskware.de 10.99.12 NetBSD 10.99.12 (UNPLUGED) #627: Mon Feb 24 11:21:12 CET 2025 martin%seven-days-to-the-wolves.aprisoft.de@localhost:/work/src/sys/arch/evbarm/compile/UNPLUGED evbarm
Architecture: earmv5
Machine: evbarm
>Description:

Side note: I guess this is "the" remaining issue with HAVE_JEMALLOC=530
on arm and mips.

Everything that uses libpthread seems to be broken on armv5 with new
jemalloc.
