--- Comment #3 from homgran <matt at gneilson dot plus.com> ---
Interesting... I've just tested Janus' reduced/modified version with "GNU
Fortran (GCC) 4.8.1 20130404 (prerelease)", and it does indeed compile cleanly.
However, my sample code ('test.f90', attached to the original post) produces an
ICE when attempting to compile with "GNU Fortran (GCC) 4.8.1 20130404
(prerelease)".
