I don't see anything like that.  Here's my output:

  addr=0x011b4ea5
  addr=0x011b4ea5
  addr=0x012329a8
  disp=del
  disp=del
  disp=keep
  enabled=y
  enabled=y
  enabled=y
  file=../lib/allocator.h
  file=../lib/careadlinkat.h
  file=../lib/ignore-value.h
  file=../lib/intprops.h
  file=../lib/intprops.h
  file=../lib/intprops.h

IOW, all the duplicates I see are header files.  Not a single .c file
shows up, not even if I change "head -15" into "head -100".

Maybe you should upgrade, I dunno.  I use 7.4.1, FWIW.

Or maybe GCC versions later than what I have do that.

Here too, but that's expected (and necessary).
