I get a similar problem with the pure MacOS X port (building from 
MacOSX/) unlike building from the Unix/ directory with SDL support. I 
have not really investigated why, neither did I try to set the 
emulation to 030. Actually the crash can occur at any time.

It could be a miscompilation (which is not unsual on that platform), or 
some stack alignment problem but there should not be any nowadays. i.e. 
reminder: it works with a Unix/ + SDL port.

Does it work with 030+FPU?

BTW, I also tried to fully build from the command line. It works on 
PPC, but B2 dies the same way on Intel. Some flags may be missing on 
Intel side. Anyway, I'd probably commit this too as I'd prefer building 
the whole emulator from command line and only use e.g. Interface 
Builder to update the GUI.

I tried to gdb it but it was not very useful. :-(

I may try again to debug on this weekend.
