Not sure about the details but I suspect this is something to do with the way we have to jump through hoops to allocate the code buffer on MacOSX. You could stick some printfs around: alloc_code_gen_buffer_splitwx_vmremap and alloc_code_gen_buffer_anon AIUI we have to allocate a non-executable but writable buffer for the code and then remap an executable view of the same region to execute the generated JIT code. Maybe being a signed binary adds more restrictions on which OS apis can be called? -- Alex Bennée
