sayan paul 9de9cd17e7 malloc: New test to check malloc alternate path using memory obstruction 
The test aims to ensure that malloc uses the alternate path to
allocate memory when sbrk() or brk() fails.To achieve this,
the test first creates an obstruction at current program break,
tests that obstruction with a failing sbrk(), then checks if malloc
is still returning a valid ptr thus inferring that malloc() used
mmap() instead of brk() or sbrk() to allocate the memory.
