Do not terminate the process with ASan on allocator returning 0

ASan allocator will not crash and return 0 in case of out-of-memory.

Currently *null* will be returned for the following cases inside internal
allocator:

- Requested size is more than 3 << 30 for 32bits and 1 << 40 for 64bits.
- Requested size overflow.
- RSS limit excided
- mmap syscall returns 0
