Betwixt r170417 and r170432 there aren't many commits. I only see two which at
a glance could be related:

Unless, it is one of those innocently looking patches ...


The Fortran patch is an I/O patch, which fixed a 4.3/4.4/4.5/4.6 regression for
list-directed, formatted reading from sockets.

(Without access to
http://www.spec.org/cpu2000/CFP2000/187.facerec/docs/187.facerec.html it is
kind of difficult to debug it; when I quickly searched, I also could not find
the source.)
