Tests 14 and 15 in t/examples/shootout.t fail on Linux/PPC because jit_set_args_pc does not handle floating point arguments correctly. I poked at the code a little bit, but PPC is different enough with its relative wealth of registers that I couldn't fix things trivially. (I'm not even sure I can debug the problem properly; copying and modifying the code from the x86 JIT doesn't do it.)
Does this test work correctly on Mac OS X? -- c
