You should monitor the program with strace while it fails (last few syscalls). You can breakpoint at exit() and run `cat /proc/pid/maps` to show us the vma layout of the task. Then we'll see why it's failing. With CONFIG_1G in 2.2.x or 2.4.x (confinguration option doesn't matter) you should at least reach something like 1.5G.
