AMD CPU bug!

Does anyone remember Intel Pentium bug? Well, now we have one other CPU bug from AMD.

The description:

And the confirmation from AMD:

Basically, under very special conditions, the processor will incorrectly update the stack pointer. The most common symptom is a spurious segmentation fault.

This is too hot. Will there be recalls?
