Hi,
I am seeing a core dump in RSA_check_key() function. The backtrace is as below.
I am unable to understand what is causing the issue. The core dump is
intermittent (not always reproduced).
Could someone please provide any pointers if I am missing any check?

Thanks,
Nilesh
P.S.
The code generating crash is:
// fp is a valid pointer to the private key file in PEM
format.
RSA *rsa = (RSA *) PEM_read_RSAPrivateKey(fp, NULL, NULL, NULL);
if (!rsa) {
return -1;
}
if (RSA_check_key(rsa) != 1) {
RSA_free(rsa);
rsa = NULL;
}
Back trace:
