I'm using Linux with the architecture "x86_64" (model: 15.43.1 "AMD Athlon(tm) 64 X2 Dual Core Processor 4200+").

This means you have debuginfo package for a different version of glibc than you have installed on your system.
I admit that the package "glibc 2.11.3-12.17.1" was installed. I have downgraded it temporarily to the version "2.11.3-12.15.1" to match it with the available debug information.
As the bug is not in glibc, you don't need that debuginfo anyway.
I would like to be sure that I do not blame the wrong software component.
