Bug#647896: regression (?): libc6: Broken thread local storage (TLS) initialization
Package: libc6
Version: 2.11.2-10
Severity: serious
Justification: Policy 10.2
Regarding the bug on this page: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=637239
It clearly states: "There is a bug with TLS in libc6, beginning with 2.12."
However, I seem to be having similar problems on Debian stable with 2.11:
# dpkg --list | grep libc6
ii libc6 2.11.2-10 Embedded GNU C Library: Shared libraries
ii libc6-dev 2.11.2-10 Embedded GNU C Library: Development Libraries and Header Files
ii libc6-i686 2.11.2-10 Embedded GNU C Library: Shared libraries [i686 optimized]
ii libc6-xen 2.11.2-10 Embedded GNU C Library: Shared libraries [Xen version]

After a bit of research, I found that this error is tied back to some issues in libc6, as per the above bug report. I also found on the Gentoo mailing list that the bug has existed since 2005: https://bugs.gentoo.org/show_bug.cgi?id=353224 - Starting from comment 14.
