Infinite mac crashes with address error

[jllipatz]

Hello,

In my application (a developpement tool actually) I have handlers for various exceptions in MC68000 code, TRAPs are correctly handled on infinite Mac but apparently not bus errors. Following instruction doesn't activate my handler:
MOVE $40000000,D0

but rather stops infinite mac with following message in console:
RuntimeError: index out of bounds

On ordinary Macs I get something like that (and correct the failure):

Surely, but what I flag here is that the emulation has a hole: one of the exception vectors is not used. Consequences are rather minor but with MasOS 9.2 such exceptions don't crashes the Mac nor ask for a restart. And that is a good thing to have some chance to save the work done elsewhere.
