Linux gcc4.4 fix: stop crashing when loading flash.

Linux gcc4.4 fix: stop crashing when loading flash.
sizeof(bool) is 1 byte in opt mode.  We pass a pointer to a bool to a function expecting a void*.  It writes 4 bytes of data to the pointer, rather than 1 byte.  This corrupts the stack bordering the bool stack variable, thereby manifesting itself as a crash.  In particular, we were overwriting a spilled register (which stored an object pointer) with 3 bytes worth of zeros.  After returning from the function, we called into the object, which now had the wrong pointer.
