I can confirm the segfault with 4.5, 4.6 and 4.7 (trunk) on the test case in
comment #0:


subroutine sub
  common n,z
  character(n) z 
end


However, when removing the subroutine line, I get:

  common n,z
            1
Error: 'z' at (1) must have constant character length in this context


And on the following variant

subroutine sub
  common z
  character(n) z 
end

one get's a different error:

  character(n) z 
            1
Error: Variable 'n' cannot appear in the expression at (1)
