I think this is the one you want. I kept it for future ref.

In Performer2.2 we changed pfSqrt and pfSinCos to macros to use
the math library functions. These finally got fast enough in the
math library that Performer didn't need special versions and so
you don't want even the additional hit of a subroutine call slowing you down!
Your problem implies that you have object files that have not been
recompiled with Performer2.2. Note that this is particularly dangerous
if you use C++ since the C++ clas sizes changed in Performer2.2 and will NOT
be binary compatible with previous releaseeees.

If you didn't recompile, then you are running against 2.0 or 2.1 libraries.
Performer2.2 includes 2.0.5 and 2.1.3 compatibility subsystems that include
some additional bug fixes for 2.0 and 2.1 respectively.
If you see a change in behavior, it is possible that you were actually
benefiting by and depending on some bug that was fixed in 2.0.5/2.1.3 or
else have some memory dependent bug of your own that is tickled by
the changes.
