> Unfortunately I don't know C and cannot write testcase to allocate 2Gb via mmap .__. Testcase with malloc() works without crashes.

mmap_test.c:

#include <stdio.h>
#include <sys/mman.h>

int main() {
    printf("%p\n", mmap(0, 2ul * 1024ul * 1024ul * 1024ul,
        PROT_READ | PROT_WRITE, MAP_PRIVATE | MAP_ANON, -1, 0));
    return 0;
}

Compiling: gcc mmap_test.c -o mmap_test
