[Bug fortran/27786] New: Bad interaction between Cray pointer, assumed-size array and bounds checking

[fxcoudert at gcc dot gnu dot org]

This reduced testcase is originally from the testsuite
gfortran.dg/cray_pointers_2.f90. It generates an incorrect out-of-bounds error
message when run with bounds-checking enabled.

$ cat cray_pointers_2.f90 
  integer targ(2)
  integer pte
  pointer(ptr,pte(*))
  ptr = loc(targ)

  targ(2) = -1
  print *, pte(2)
  end
$ gfortran -fbounds-check -fcray-pointer cray_pointers_2.f90 && ./a.out
Fortran runtime error: Array reference out of bounds
