CRYPTO_add_lock segfault when attempting to open X509 CSR

[Nikita Koptelov]

Good day,
I'm trying to use openSSL libs to parse certificate request, but something
goes wrong.
The thread throws segfault around:


0x7ffff77fee0a  <+0x007a>         mov    %r8d,%ecx

0x7ffff77fee0d  <+0x007d>         mov    %r13d,(%r12)

0x7ffff77fee11  <+0x0081>         callq  0x7ffff77fe000 <CRYPTO_lock@plt>


in CRYPTO_add_lock when using d2i_X509_REQ_fp(). Could anyone help me with
the problem?

Code:

    FILE* fp;

    FILE* fperr;


    fp = fopen(path,"r");

    if (fp != NULL)

    {

        fperr = fopen("/home/utrk/err","w");

        X509_REQ *cert;

        d2i_X509_REQ_fp(fp,&cert);

        if (!d2i_X509_REQ_fp(fp,&cert))

        {

            ERR_print_errors_fp(fperr);

        }

        fclose(fp);

        fclose(fperr);

    }
