Declaring variables mid-function changes results

Calling a dummy function makes the error not happen.

I wish I could provide a working example other than a description of "screwed up rotation". This is very strange.

I am running in Strict mode, by the way.

	Method Rotation:TQuat()		
		Local mult:Float
		Local fourWSquaredMinus1:Float = +ix+jy+kz
		Local fourXSquaredMinus1:Float = +ix-jy-kz
		Local fourYSquaredMinus1:Float = +jy-ix-kz
		Local fourZSquaredMinus1:Float = +kz-ix-jy
		Local biggestIndex=0
		Local fourBiggestSquaredMinus1:Float=fourWSquaredMinus1
		If fourXSquaredMinus1 > fourBiggestSquaredMinus1
			fourBiggestSquaredMinus1 = fourXSquaredMinus1 
			biggestIndex=1
		EndIf
		If fourYSquaredMinus1 > fourBiggestSquaredMinus1
			fourBiggestSquaredMinus1 = fourYSquaredMinus1 
			biggestIndex=2
		EndIf
		If fourZSquaredMinus1 > fourBiggestSquaredMinus1
			fourBiggestSquaredMinus1 = fourZSquaredMinus1 
			biggestIndex=3
		EndIf
		Local biggestValue:Float=Sqr(fourBiggestSquaredMinus1+1.0)*0.5
		mult=0.25/biggestValue
		Local x#,y#,z#,w#
		Select BiggestIndex
			Case 0
				w#=BiggestValue
				x#=(jz-ky)*mult
				y#=-(kx-iz)*mult
				z#=-(iy-jx)*mult
			Case 1
				x#=-BiggestValue
				w#=-( jz - ky )*mult
				y#=( iy + jx )*mult
				z#=( kx + iz )*mult
			Case 2
				y#=BiggestValue
				w#=-(kx-iz)*mult
				x#=-(iy+jx)*mult
				z#=(jz+ky)*mult
			Case 3
				z#=-BiggestValue
				w#=(iy-jx)*mult
				x#=(kx+iz)*mult
				y#=-(jz+ky)*mult
		EndSelect
		KeyHit(KEY_N)
		Return quat(-x,y,z,w)
	EndMethod
	
	Function KeyHit(blah)
	EndFunction
