[issue5504] ctypes should work with systems where mmap can't be PROT_WRITE and PROT_EXEC

Adam Goode added the comment: Currently there is an issue where allow_execstack implies allow_execmem. Even though allow_execmem is default to off, allow_execstack is default to on. If this issue is fixed, or if the administrator sets allow_execstack to off, ctypes will fail. Try this as root

[issue5504] ctypes should work with systems where mmap can't be PROT_WRITE and PROT_EXEC
