Hi John,

    just got a crash switching back to the Squeak VM window after working in a terminal window running a compile, while my Squeal VMMaker image was generating sources.

Exception Type:  EXC_BAD_ACCESS (SIGBUS)
Exception Codes: KERN_PROTECTION_FAILURE at 0x0000000000000000

VM Regions Near 0:
