Forgot to change that: The first is working, the second is failing.


If one looks at the original dump, the only difference is nesting:


While the working version has:

sub (integer(kind=1)[0:D.1600] * restrict a, integer(kind=4) & restrict n)
{
  ....
  {
     // setup .string and other initialization
  }
  {
     // memmove etc.
  }
  {
     // write
  }
}


While the failing version uses:

sub (integer(kind=1)[0:D.1600] * restrict a, integer(kind=4) & restrict n)
{
  ....
  {
     // setup .string and other initialization
    {
       // memmove etc.
    }
    {
       // write
    }
  }
}
