Hi Toni, debug related oddity.

Code:

Code:

	move.l	#$7fff7fff,$dff09a
	rts

Before launching the previous one I insert in the debugger:

w 0 dff09a 4 w 7fff7fff.l

Code:

>w
 0: 00DFF09A - 00DFF09D (4)  W  =7FFF7FFF.l CPU

Results.
Quickstart A500 (000):

Memwatch 0: break at 00DFF09C.W  W  7FFF7FFF PC=00C077B8 CPUDW (000)

Quickstart A500 (010): save as above
Quickstart A1200 (020): does not trigger
Quickstart A1200, Blizzard 1230 (030): does not trigger
Quickstart A1200, Blizzard 1230 (030, MMU):

Memwatch 0: break at 00DFF09C.W  W  7FFF7FFF PC=47012772 CPUDW (000)

Quickstart A1200, Blizzard 1240 (040, no MMU):

Memwatch 0: break at 00DFF09A.L  W  7FFF7FFF PC=47012768 CPUDW (000)

Cheers.
