Description Francois-Xavier Coudert 2006-05-24 21:37:51 UTC 
I ran the gfortran testsuite with -fbounds-check and found a few failures (on i686-linux), among which was gfortran.dg/aliasing_dummy_1.f90. Here is a reduced testcase:

program test_lex
  type :: dtype
    character*5 :: word
  end type dtype

  type :: list
    type(dtype) :: list(1)
  end type list

  type(list) :: table

  call foo1 (table%list(1)%word)

contains

  subroutine foo1 (slist)
    character(*), dimension(*) :: slist
    write (slist(1), '(i5)') 0
  end subroutine foo1

end program test_lex

$ gfortran -fbounds-check bug.f90 && ./a.out 
Fortran runtime error: Array reference out of bounds

I bet $ 100 (or a beer at the GCC summit if you come) that the problem is with
dimension(*)

Which means this is a dup of bug 19777.

Right you are. Closed as duplicate.

Well, my employer has nothing to do with gfortra, so I won't be coming. But if you ever come to Paris, I'll offer you a beer!
