Yes, 8.2 is quite an old version.

Thanks. However, your build is optimized, whereas mine isn't. This
has a significant effect on the backtrace (static functions are
inlined and don't appear in the backtrace). Please reconfigure with
CFLAGS='-O0 -g3' (and the rest of the switches as you used them for
this build), and show the backtrace after rebuilding.
As I established earlier, in
https://debbugs.gnu.org/cgi/bugreport.cgi?bug=47067#80
https://debbugs.gnu.org/cgi/bugreport.cgi?bug=47067#83
the code which GDB fails to identify with any symbols calls Emacs
primitives via freloc.link_table. Where is the C source for this
code? If there is no C source, then how is that code generated?

And if you type "C-s sleep"?
