Ok so it seems to be a 64-bit symbol table (according to
https://docs.oracle.com/cd/E53394_01/html/E54772/ar-3head.html):
> A 64-bit archive symbol table sets ar_name to the string “/SYM64/”,
padded with 9 blank characters to the right."
We should skip it. I will make a patch.
Thanks for the report!

It validated without any errors. So I can't reproduce it right now. I'll try
the patch sometime later today when I have the other laptop with me.
Sylvain, do you have any ideas on what difference may be causing this? I'm
pasting gcc and ld versions but I'm not sure if they're relevant at all.
2016-11-11 11:55 GMT-05:00 Sylvain Henry <[email protected]>:
My bad, in fact we do.
Could you try with the attached patch? It shows the failing filename in the
archive.

Did this line get truncated? It might help to have the rest of it.
