[Bug fortran/35723] New: Can't use run-time array element in character declaration


The following program gives an error message for valid use of
an array element in an expression for an automatic character
array.  

The error message is repeated twice.

Changing from a run-time subscript in the parameter array to a
constant fixes the problem.
