Did it affect any languages other than PHP? The linked article suggests that it was PHP only (and this agrees with zend_strtod being the problem function and not any C library implementation of strtod(3)).
It affected a whole bunch of languages, libraries and compilers, apparently because the strtod() implementation in question has been a popular copy&paste piece.
This guy here over at http://blog.andreas.org/display?id=9 mentions at least: "Android libc, gcc libio, gcc java runtime, newlib libc, GNU Mono, Apple's libc, mozilla"
It was particularly nasty because it could easily be exploited simply by putting that specific decimal number into a web form or whatever, and for each request a thread on the backend server would lock a CPU to 100% usage until sysadmins discover and kill those threads, worst case.
It affected Java too. I don't remember if it affected all versions of Java or not, but I reproduced (and fixed) it in my Let's Play TDD screencast series. Here's the episode: http://www.jamesshore.com/Blog/Lets-Play/Episode-89.html The "double of death" part starts at 3:33.
