>Description:

On some core files, like the ones generated by the Xorg server in PR lib/51749,
gdb does not properly map core memory and can not produce ussable backtraces.
It also seems to be missing all symbols, e.g. "list main" does not work.

I have uploaded that core, debug-info and binary to:
