Yeah thanks.. It's my bad to miss such a simple thingy...
The problem was actually my program(more complex than the test case) is
giving the same memory leak. Seems I have to look at my code more
carefully.

Hi,
I found that there is a memory leak in the function
PEM_read_bio_X509();
Herewith I've attached the valgrind trace(with flags --tool=memcheck
--leak-check=full --show-reachable=yes ) and a sample test case.
Is this a known issue or have I missed some steps?

I think the problem is that you haven't freed the X509 structure
which was created when you read the certificate.
So your program needs something like
if (cert) {
X509_free(cert);
}
at the end.
