Need help with square root function (sqrt) on MCF52211

I'm having problems getting the sqrt (or sqrtf) function to work properly.
My targer processor is MCF52211.  CodeWarrior version 5.7.0.

When I run using sqrt, the result is always 20.0 and and the exception handler is entered, resulting in the error: "Access Error: Error on operand write".

When I run using sqrtf, the result is a very large, incorrect number.

I've tried using different msl libraries. 
Is there a specific library I should be using or a setting somewhere that I am missing?
