of service (memory corruption) or possibly have unspecified other
impact by using the same variable for multiple arguments.

It's probably less confusing to say that Fedora 15 and 16 are not affected by this issue as they ship fixed upstream version.  F-15, however, included php 5.3.6 at GA and as this issue was first fixed upstream in 5.3.7 (see comment #3), it probably was affected by this issue for some time.
