This bug is very likely a bug present in old glibc versions. It has been
brought to light when enabling TLS support in openblas and not by a new
glibc version.

Right now the bug has been workarounded by disabling TLS support in
openblas. The way to handle this bug is to write a small testcase that
can be forwarded upstream. It's not an easy task though.
