This is the most likely problem - you are free()ing memory that has already
been free()d. Maybe you are free()ing memory

In openssl-0.9.7g/crypto/asn1/t_509.c, there is this function:

Has anyone tried the PKITS suite:

against OpenSSL?
I'm planning to use some of those tests, and it would help if I knew what
tests are known to fail.

I'm trying to do detached CMS signatures and verification using the
PKCS7_sign() and PKCS7_verify() functions. It appears to work OK, except that
my test case for a zero length array fails to verify() - looks like the
signature is OK though.
The documentation suggests that PKCS7_verify() isn't

There is an openssl tool to do so - see:

I'm trying to determine the length (in bits) for my DSA and DH keys. I'm
happily using RSA_size() for RSA keys, and I assumed that DSA_size and
DH_size would do equivalent operations (based on the man page for
BN_size_bits, which states 'If you want to know the "key size" of such a key,

As it turns out, I do have a EVP_PKEY, so this is just what I needed.
