							 If that doesn't
   work, then you should try turning off your optimizer and seeing what
   happens. If the code works after that, then your optimizer is buggy, and
   you should report the problem to your vendor.

Oh come now.  Lots of programs have bugs which only appear when
optimised.  For instance they might reference uninitialised locals,
which may overlay different stack garbage when optimised or not.

Now I don't know if this is true of your program or not; I've never
seen it.  I just don't like blanket statements like that one.
