Something else is going wrong. Is that the only valgrind error? Are you sure you didn’t free the object in your code?

Subject: Re: [openssl-users] freeing of X509_CRL object
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)
==31919== by 0xB355537: asn1_do_lock (tasn_utl.c:79)
==31919== by 0xB352767: asn1_item_embed_free (tasn_fre.c:88)
==31919== by 0xB3528D4: ASN1_item_free (tasn_fre.c:20)

The print routine does not free anything.
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.
