Hi Kamil,

thank you for your mail. Did you had a look at

https://github.com/cschwan/sage-on-gentoo/issues#issue/40 ?

The interesting stuff was found out by Martin von Gagern, on January 30, 2011. 
Its turns out that the problem is a bug in glibc, see

https://bugs.gentoo.org/353224

and

http://sources.redhat.com/bugzilla/show_bug.cgi?id=12453

which are hopefully fixed soon.

Cheers,

Christopher
