[Patch, fortran, 64674, v2] [OOP] ICE in ASSOCIATE with class array

[Andre Vehreschild]

Hi,

so here is the update on pr 64674. Besides adapting to current trunk nothing
has changed from the previous version. The links for getting the patches this
one depends on are:

PR65548 v5: https://gcc.gnu.org/ml/fortran/2015-05/msg00123.html and
PR44672 v6: https://gcc.gnu.org/ml/fortran/2015-05/msg00124.html

Bootstraps and regtests fine on x86_64-linux-gnu/f21.

Any comments?

- Andre
