// Normally, the runtime libraries like to mess with the memory returned by malloc(), 
// which can create problems trying to repro bugs in debug builds or in the debugger.
//
// If the debugger is present, it initializes data to 0xbaadf00d, which makes floating
// point numbers come out to about 0.1.
//
// If the debugger is not present, and it's a debug build, then you get 0xcdcdcdcd,
// which is about 25 million.
//
// Otherwise, you get uninitialized memory.
//
// In here, we make sure the memory is either random garbage, or it's set to
// 0xffeeffee, which casts to a NAN.
