I have a fix which I am testing.

Yes this was a bug in fold_indirect_ref and not in the fortran front-end (it could also effect Ada too but I 
have no test case for Ada).

Basically what happens is that the fortran front-end creates an array which has a lower bound of 1 and 
then casts the reference to one of those to the pointer type of the type (of what is in the array) and the 
dereferences it.  fold_indirect_ref would get the lower bound wrong which causes us to create wrong 
code.
