Hmm, interesting. The current bug I am investigating in the one that makes
B2 crashes in Direct Addressing mode with Apple Personal diagnostics. It
looks related to 68040 emulation as it works under 68030.

Probably "someone" is trying to access above the SratchMemory area. It
could be a compiler bug too. Please try compiling with optimizations off
(edit the CXXFLAGS in Makefile).

Are you operating in windowed mode or DGA? Still crashes even in 68030
mode with/without FPU?

VOSF is mandatory for Direct and Real Addressing modes. B2 will work for
you if configured with --enable-addressing=banks. But that's not an
option, it has to work in other modes too.

I am looking forward to helping you but I can't reproduce here on my
system (Mandrake Linux 8.1 or Cooker). So may I suggest you compile B2
with cxmon builtin and the attached patch?

Have you tried with --diable-xf86-vidmode ? --enable-fpe=uae ?

Bye,
Gwenole.
