--- Comment #3 from Arseny Solokha <asolokha at gmx dot com> ---
I see the same issue w/ the following snippet compiled w/ -O2
-ftree-parallelize-loops=2 -floop-nest-optimize -g:

int te[9];

void
dt (int cz)
{
  while (cz < 1)
    {
      int xy;

      for (xy = 0; xy < 9; ++xy)
        te[xy] = 0;

      ++cz;
    }
}

% gcc-8.0.0-alpha20180211 -O2 -ftree-parallelize-loops=2 -floop-nest-optimize
-g -c pr84404.c
/tmp/ccfu80w2.s: Assembler messages:
/tmp/ccfu80w2.s:700: Error: leb128 operand is an undefined symbol: .LVU12

as of r257571.

GNU as 2.30 seems to be the key here.
