The compiler might be doing type-based aliasing to re-order the
functions, if one uses float, and the other int, say.

However, I still don't see how the compiler can do this. Timers 
call into functions that are dllimport, and those functions can 
have arbitrary side effects -- especially in a version of the 
DLL that's not released yet. Thus, no amount of alias analysis 
can allow the compiler to re-order the operations like that, so 
I'd say it's a real bug.

Now, if it's really a bug, how come we're not seeing this all 
over the place? Seems like it would cause pretty much nothing at 
all to actually work...

Cheers,
