Correct (AFAICT).

Something like this, perhaps?

      /* Check for FDEs with zero initial_location.

         Such FDEs could come about when linker discards a section (either
         a COMDAT section when the linker selects a different section
         from the same group, or just a regular section discarded due
         to --gc-sections), but keeps the corresponding .debug_info.

	 The linker sets the relevant FDE.initial_location to zero, but
	 doesn't zero the FDE.address_range because there's no relocation
	 there.  It's (offset, length), not (start, end).

... rest as before ...
