Not a bug.
I believe the term 'reverse dependency' is used generally. You upgrade one
software upon which a second software depends and that second software
breaks. In this case R is the second software and gcc is the first. You
fix it just as you did by rebuilding the second software.
See
http://en.wikipedia.org/wiki/Dependency_hell
and links there for info on why softwares use such dependencies.
