in thread SUPER delegation fails because class name getting munged (somehow?)

Flipping of more than one bit is possible and probably quite common, but to have bits flip so that always a substraction of 1 comes out is just very unlikely. I did check the other two examples and while one was similar to the case I posted about, the other one was just a flip of the lowest bit.

    Not necessarily. The corruption could be in the address used by some unrelated decrement.

    It does seem rather predictable for hardware memory corruption, though.
