Based on the information you provided, I don’t have any other advice. The print routine does not free the CRL. You must be free’ing it twice. Perhaps run under a debugger with a breakpoint

Subject: Re: [openssl-users] freeing of X509_CRL object
Yes, I am freeing
_x509crl using X509_CRL_free after using in X509_CRL_print.
Above valgrind error is for free operation, is it wrong?

Something else is going wrong. Is that the only valgrind error? Are you sure you didn’t free the object in your code?
Any idea, why
is X509_CRL_free reporting below error with valgrind?
Valgrind output:
==31919== Invalid read of size 4
==31919== at 0xB475EF2: CRYPTO_atomic_add (threads_pthread.c:155)

In my program,
converting X509_CRL object to string format using
X509_CRL_print and BIO_get_mem_data. after that if de-allocate _x509crl using
X509_CRL_free. it is crashing with below reason.

not sure if
X509_CRL_print de-allocates some part of _x509crl , external freeing of X509_CRL again leading to double free?
Please help on this issue.
