This patch fixes backtrace/1435.  The failure occurs when main
immediately follows a function (say foo) which has its epilogue
optimized out by the compiler.  In that case the backtrace will be
terminated prematurely since get_frame_pc on foo's frame will return
the address of the first instruction of main.  This can be fixed by
using get_frame_address_in_block.

Ok to check this in?

Yes, but with more comments :-)

from  Mark Kettenis  <kettenis@gnu.org>

	* frame.c (get_prev_frame): Use result from
	get_frame_address_in_block instead of get_frame_pc as argument to
	inside_main_func.
