Is your program using MAP_FIXED? You can use blink -s to system call trace and find out. Chances are it's requesting fixed memory that overlaps with memory Android OS or Bionic Libc inserted into the address space. You need to pass the -m flag to disable the linear memory optimization when running such programs.
