With a newer compiler version I am guessing, they currently link and
work correctly depending on your platform and/or compiler version :-)

Why didn't you just put the new .eh_frame_hdr in like the others ?
They are included in the output already and since you moved _edata

Could you try the attached patch and see if that works ?
Thanks,
