Bus error on 32bit OSX, not 64bit

[Jacob Carlborg]

This code:

Will result in a bus error when compiled as 32bit. Three ways the bus 
error won't happen:

* If I compile as 64bit everything works fine
* If the function "foo" is moved inline in the "main" function 
everything works fine
* If store the return value of "fp" in "foo" in a temporary variable and 
then return it
