Hi All, 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. 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) 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. Regards, Raghavendra
