Sorry, that is not strictly correct. According to the man page:
"The alloca() function allocates size bytes of space in the
stack frame of the caller, and returns a pointer to the
allocated block. This temporary space is automatically freed
when the caller returns."
Now this is the real reason:
" If the allocated block is beyond the current stack limit,
the resulting behavior is undefined."

Hi All,
If you use alloca inside a function when it retuns from
function it will be resulting in memory leak. Thats why
its discouraged to use.
