The function in question is:

static void

           time_t *sec, unsigned *usec)
{
  unsigned long long ullsec;

  *sec = tval / hz; <---- this is line 2534
  ullsec = *sec;
  tval -= ullsec * hz;
  /* Careful: if HZ > 1 million, then integer division by it yields zero.  */
  if (hz <= 1000000)
    *usec = tval * 1000000 / hz;
  else
    *usec = tval / (hz / 1000000);
}

This has been marked as a duplicate of PR42690, which in turn has been closed
as fixed.

But the problem in this report still happens with gcc 
Revision: 167509
when using gold as linker.

So it seems that this bug should be reopened.

I think you should open a bug report against gold.

Gold was updated to handle this well for binutils 2.11.1, so H.J.'s branch.
We still have issues with mainline GNU LD.  Dave, what about getting this fixed
the gold way?

Seems worth investigating.  I'll take a look at it starting tomorrow sometime.

Closing this PR, since, as discussed, it is a binutils bug:
