Hi,

I my program , converting X509_CRL object to string format using X509_CRL_print and BIO_get_mem_data. After that if i use X509_CRL_free(_x509crl) it is crashing 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 0xB3528D4: ASN1_item_free (tasn_fre.c:20)

not sure if X509_CRL_print using nested pointers of x509_CRL object and freeing them, external freeing of X509_CRL again leading to double free?

Please help on this issue.

Raghavendra
