Comment 1 for bug 919202

The reason for "useless" stack trace is a GDB bug:
http://sourceware.org/bugzilla/show_bug.cgi?id=9538

You should be able to get a more useful info by using explicit

  add-symbol-file /usr/lib/debug/lib/x86_64-linux-gnu/ld-2.15.so <ld-linux-load-address>

(where ld-linux-load-address is available from "info shared")
