Description

With the following example, gfortran has runtime error:

program main
  character(len=5) :: s
  write(s, '(3I0)') [11, 22, 33]
  print '(a)', s
end program main

since the written string is longer than string s.

It would be nice to have a check that will determine such situations (especially when runtime values are used).
