Sounds related to:
https://bugs.busybox.net/show_bug.cgi?id=2089
Yes, it is definitely related. I don't understand why the bug is RESOLVED
as WONTFIX. Of course it is nice that it is not an issue with NPTL, but as
far as I can see in Config.in NPTL is still considered unstable/immature.
IMHO, suggested patch is short, fix exactly what was broken, does
not touch code for NPTL (TLS) case.
The bug makes uClibc 0.9.32 as well as 0.9.31 unusable with
linuxthreads.old. I've not checked linuxthreads. IMHO, it would be
really nice if it is finally fixed in upcoming releases.
Thanks,
Andrew.
