[Bug fortran/31197] [4.3/4.2 regression^2] TRANSPOSE/RESHAPE and strings

[fxcoudert at gcc dot gnu dot org]

Hey, this has turned into an ICE on today's trunk. Cool, it's gonna be easier
to work on! :)

As I pointed out in http://gcc.gnu.org/ml/fortran/2007-04/msg00295.html, this
makes it a potential double regression, which is nasty.
