--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Started with r237429.  Don't know why this has anything to do with libgfortran
powerpc64le-linux bootstrap, that worked for me just fine in 8.3-rc1.

Slightly adjusted testcase:
struct S { double a, b; } d;
int e;
double f;

void
foo ()
{
  _Complex h;
  while (e)
    {
      f = h;
      *(struct S *) &h = d;
    }
}
