No obvious wrong line numbers in the '-fdump-tree-original-lineno' output for
the module:

s1 (integer(kind=4)[0:D.1561] * restrict a, integer(kind=4) & restrict n)
{
  integer(kind=8) ubound.0;
  integer(kind=8) ubound.1;
  integer(kind=8) stride.2;
  integer(kind=8) ubound.3;
  integer(kind=8) stride.4;
  integer(kind=8) ubound.5;
  integer(kind=8) stride.6;
  integer(kind=8) offset.7;
  integer(kind=8) size.8;
  integer(kind=8) D.1561;
  bit_size_type D.1562;
  <unnamed-unsigned:64> D.1563;

  ubound.0 = (integer(kind=8)) [bugs.f90 : 4] *n;
  stride.2 = NON_LVALUE_EXPR <ubound.0>;
  stride.2 = MAX_EXPR <stride.2, 0>;
  ubound.1 = (integer(kind=8)) [bugs.f90 : 4] *n;
  stride.4 = stride.2 * NON_LVALUE_EXPR <ubound.1>;
  stride.4 = MAX_EXPR <stride.4, 0>;
  ubound.3 = (integer(kind=8)) [bugs.f90 : 4] *n;
  stride.6 = stride.4 * NON_LVALUE_EXPR <ubound.3>;
  stride.6 = MAX_EXPR <stride.6, 0>;
  ubound.5 = (integer(kind=8)) [bugs.f90 : 4] *n;
  size.8 = stride.6 * NON_LVALUE_EXPR <ubound.5>;
  size.8 = MAX_EXPR <size.8, 0>;
  D.1561 = size.8 + -1;
  D.1562 = (bit_size_type) size.8 * 32;
  D.1563 = (<unnamed-unsigned:64>) size.8 * 4;
  offset.7 = (~NON_LVALUE_EXPR <stride.2> - NON_LVALUE_EXPR <stride.4>) -
NON_LVALUE_EXPR <stride.6>;
  [bugs.f90 : 7] (*a)[(((NON_LVALUE_EXPR <stride.2> + 1) + NON_LVALUE_EXPR
<stride.4>) + NON_LVALUE_EXPR <stride.6>) + offset.7] = 0;
