qemu @1.6.0+target_i386+target_m68k+target_mips+target_ppc+target_sparc+target_x86_64 - qemu-system-sparc broken - compiler issue?

[d0wntime]

When I use the qemu-system-sparc built by MacPorts, it freezes during the emulated machine's startup process. When I build it using gcc-apple-4.2, I have no such problem.
