[Bug fortran/25401] New: improper runtime bounds check error when using arbitrary length arrays

[cummings at cacr dot caltech dot edu]

I am compiling a Fortran 77 program with gfortran 4.0.2 and the -fbounds-check
flag.  When the program runs, I get a message "Fortran runtime error: Array
reference out of bounds".  The same program runs just fine when compiled with
either g77 3.x or g95 4.x and the -fbounds-check flag.  The gist of the problem
is that the runtime system is reporting an out-of-bounds error when accessing
an element of a character string array within a subroutine.  The character
string array is declared in the main program to contain 80 strings, each of
length 80 characters.  The array is received in the subroutine as an arbitrary
length array, using the asterisk notation.  I will attach a simple program that
illustrates the problem.
