Same in EL6.  The changelog for this package says:

* Wed Mar 16 2011 Adam Jackson <[log in to unmask]> 7.4-15.el6_0.1
- cve-2011-0465: Sanitize cpp macro expansion. (CVE 2011-0465)

which sounds like something that could indeed break .Xresources parsing.
Although in my case, not only old-style X apps lost their fonts marbles,
but so did the KDE programs, menus, etc -- which I didn't think used the
old-style X fonts at all.

After wasting 15 minutes resetting fonts in many different places, X is
usable again.  I'm sure Murphy's Law says that this bug will be fixed
tomorrow and we'll all have to re-reset things :)
