Re: [PATCH] Avoid registering empty .eh_frame sections

[Graham Stott <grahams at redhat dot com>]

Jakub,

The early return from __deregister_frame_info_bases is missing
a return value!

I'm not sure what's the correct fix is but returning ob
(which is zero at this point) looks about right.

Graham

	* unwind-dw2-fde.c (__deregister_frame_info_bases):
	Fix lossage in last change return OB.
