MIPS R5000 Watchpoint/Saved State Reload Crash

[Abystus]

Using MAME version 0.201, games that utilize the MIPS R5000 processor will crash MAME with no error if you set a watch point, and reload any saved state after it. This may apply to other processors as well, but I've noticed it only on this one due to the game I'm currently hacking (War: The Final Assault).

Steps to reproduce:

1. Save a state
2. Set a watch point
3. Reload previously saved state

Could I inconvenience you for a backtrace?

[Abystus]

Tried a few times. Either it is too taxing on my machine or crashes before the trace can even write. It is easily reproducible at least.

Any update on a fix for this one?

Cannot repro in 0.228, unless you specify a watchpoint range where this issue still happens.
