Because the processor can only halt on an instruction boundary, it must wait until the next instruction boundary. As a result, it stops on the first instruction of the exception handler. However, two special cases exist when a vector catch has triggered: 1. If a fault is taken during a vector read or stack push error the halt occurs on the corresponding fault handler for the vector error or stack push. 2. If a late arriving interrupt detected during a vector read or stack push error it is not taken. That is, an implementation that supports the late arrival optimization must suppress it in this case."]

If a fault is taken during a vector read or stack push error the halt occurs on the corresponding fault handler for the vector error or stack push. 2.
