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

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.
