OK - I got bnu210b.zip.

Made another simple source:
int
main(void)
{
  return 0;
}

And used gcc to assemble it, once with -gcoff, once with -gstabs

Used my as and the one from bnu210 to make objects, used bnu210's
objdump on all of them (*210.o are the ones built with bnu210's as)
and got the output below.
As you can see, truncation happens only with coff, and only with
the one from bnu210. So it's definitely an as problem; my guess
is that my as is/isn't a BFD assembler and bnu210's isn't/is.

== output starts here
