[B2-devel] Build report: Basilisk II works, SheepShaver doesn't link

[Joshua J. <jj...@gm...>]

I was very pleased to see Basilisk II build and run cleanly.  I also  
note that illegal instruction exceptions work as expected.[1]

On the other hand, bus errors do not.  Attempting to dereference  
0x68F168F1 (which is supposed to elicit a bus error exception, and  
does so on a real 68040) freezes the emulated machine.

Yes, I have code that deliberately does this. :-)

SheepShaver fails here:

[1] Actually, illegal instruction exceptions also worked in the 3rd- 
party build I was using, but Macsbug didn't recognize keystrokes, so  
it was effectively fatal.
