assert() only works in debug mode. So checking a successful memory allocation should not use assert().

What sort of environment are you using that returns NULL in this case?
You will get NULL here if mmap() fails. This should happen if your machine has less then 128 MiB left over or you increase the RAM size of the sandbox.
For testing I suggest you increase the sandbox memory size beyond the RAM and swap size of your computer.
Best regards
