Take a look at X509_get_subject_name and X509_NAME_get_entry.
They don't allocate any memory...
So you must NOT free the objects, which they return.
Else you free the same memory 3 times:
First you free the entries within the name,
then you free the name (and the entries again),
then you probably free the certificate, together with the name and it's
entries - 3d time!
So, my suggestion is: just drop those two lines:
> X509_NAME_ENTRY_free(ne);
> X509_NAME_free(name);
Also, there are much easier ways to retrieve the commonName from X509_NAME
than enumerating
all the entries, e.g. X509_NAME_get_text_by_NID;
