<neeraj> The implementation of munmap in rumprun/lib/librumprun_base/syscall_mman.c is probably buggy
<neeraj> the munmap(void *addr, size_t len) just does free(addr) and return 0
<neeraj> If I read man munmap correctly then only the pages who are in the [addr, addr+len)  range should be deallocated instead of de-allocating the complete allocation pointed by addr
<neeraj> In this case erlang is doing a tricky mmap alloc/dealloc, while rump's munmap() implementation deallocating the complete alloc done earlier, resulting in erlang use a deallocated memory location.
<neeraj> This later results into a memory corruption because future allocation allocates the same memory location which is used by erlang.
