Note: realloc_on_assign_2.f03 fails on current trunk when building with
--disable-bootstrap (system compiler: gcc version 4.5.0 20100604
[gcc-4_5-branch revision 160292]):

realloc_on_assign_2.f03: In function ‘test5’:
realloc_on_assign_2.f03:101:0: internal compiler error: in fold_convert_loc, at
fold-const.c:1906


Reduced test case:

program test5
  real, allocatable, dimension (:,:) :: xwrkt
  xwrkt = trs2a2 ()
contains
  function trs2a2 ()
    real, dimension (1:2,1:2) :: trs2a2
    trs2a2 = 0.0
  end function
end
