Well, there are three development "branches":

* 4.5 ("gcc-4_5-branch", which you seemingly have downloaded): Last stable
  release of GCC, which only sees regression fixes and serious fixes

* 4.6 experimental ("trunk"): The version which will be 4.6.0 in about a year,
  which is continuously being modified.

* "fortran-dev": Based on 4.6, but contains some additional fixes for
  polymorphism/OOP.

The commit in comment 10 was against fortran-dev, which fixed an additional
problem on Fortran-dev, which was revealed with your example. It does not yet
fix the initial problem - neither on Fortran-dev nor on the trunk (i.e. 4.6.0).

In the next few days, the changes from "fortran-dev" will be merged into the
trunk as "fortran-dev" fixes severals OOP-related issues (but not yet yours).

Dominique (comment 12) used a few patches on top of fortran-dev.

I think the simplest is to wait a few days and then use the 4.6 version (not
4.5_...).
