parameter-passing

Hey guys,

Something really weird is happening: when I call foo(100*1.0f), somewhere along the line that becomes 0. To verify I put a breakpoint on foo(), and it indeed is zero and it indeed gets called with 100*1.0f. The code is in Obj-C++.

Here is the calling function in XCode's GDB frontend, as you can see, score*scoreMultiplier is 100.

And here is the called function in XCode's GDB frontend, here _score is 0.
