It seems like you may be passing a float when a double was expected.
One sneaky way for this to occur is if you use new function prototypes
in one source file and old style declarations in another file.

For example:

File A:  extern void foo(float x);

File B:  void foo(x)
           float x;
         { ... }

In File A, foo is defined as you would expect (x is a float).  In file B,
x is promoted to a double.
