Tom, Can you please try with bleeding_edge revision 2489? This should make sure that the gcc flags and the target architecture are consistent. I do not have a Snow Leopard machine to test on currently, but this change should fix the confusion of gcc building for a 64-bit target when we are generating ia32 code in the JIT.
Thanks, -Ivan P.S. Also note that the x64 build is certainly not at a state where you should be testing it yet unless of course you want to commit fixes to it.
