Bug#668891: Static TLS (thread local storage) generates SIGSEGV in libc6 (GNU C-Library)
Package: libc6
Version: 2.11.3-2
Severity: important
Tags: squeeze
The "eglibc" source (eglibc_2.11.3-2.diff.gz eglibc_2.11.3-2.dsc
eglibc_2.11.3.orig.tar.gz) of the "libc6*.deb" packages contains a
patch which fixes a well known bug of older releases of the GNUC-Library
resulting in SIGSEGV on software which makes use of static tls. The can
be found in ".../debian/patches/any/cvs-dlopen-tls.diff".
For some reasons the patch has not been pushed onto the quilt stack. So
when building the "libc6*.deb" packages from source the patch is left
out rendering any software which make use of statis tls (e.g. qt-4.8.x)
useless (generating SIGSEGV).
When rebuilding the "libc6*.deb" packages with the mentioned patch
included all seems to be o.k. so far. Now I'm wondering if the patch has
been omitted by intention or if the omission is simply a bug, and I'm
wondering if the patch could be included officially?
