Summary	01749: memory.c: A log message has the incorrect address
Description	The message "warning - op-code execute on mapped I/O" shows the pc of the next instruction, not the one that caused the warning. The variable "byteaddress" holds the correct address, and could possibly be used instead.
Steps To Reproduce	This was encountered during development. You would need to find a driver that can produce this message.

CPU cores report the current PC, which may be the next instruction or in the middle of the instruction that accessed the memory. It could be improved, but would affect the performance of every CPU core for marginal gain, so it hasn't ever been addressed.
