Mirror effect

Hi Toni, a new interesting bug for you
I'm debugging some stupid code that make illegal access in 24bit memory.
I see with my eyes the illegal access but WinUAE debugger do not trigger (if you remember something similar reported in an old message but i was not able to replicate it, driving me crazy ).

Well, now i'm able.
Use my attached config (or other with z2 mem).
Open debugger: "w 0 800000", then "m 800000" and a magic 200000 mirroring appear at this location . Now "w 0" and no more mirroring.

"dm" is right:
Code:
00000000    2048K/1 =    2048K ID C32 Chip memory
00200000    6144K/1 =    6144K ID F32 Fast memory
00800000      64K/1 =      64K ID F32 Fast memory [D]
00810000    1984K/1 =    1984K ID F32 Fast memory
but every trigger in this zone no more works, redirected to mirror.

Regards,
ross
