Here's a very strange example of data corruption when passing
a character array section in the form

  call foo (a(:)(7:11))

to a subroutine even if the parameter is declared as INTENT(IN).
Furthermore, even another array gets corrupted which is intended
to hold a copy.

See testcase for details.

Cheers,
