unable to free PROXY_CERT_INFO_EXTENSION

[Matthew Rodriguez DSD staff]

I can't seem to get rid of a memory leak when I create a proxyCertInfo 
extension. I've tried calling X509_EXTENSION_free,
and then X509_EXT_cleanup. I don't think I need to do that because it is 
not a custom extension, I'm using
openssl-0.9.8a.

Here's what I've discovered so far.
The X509_EXTENSION_free is a macro that is defined by 
IMPLEMENT_ASN1_FUNCTIONS. This
gives you functions to encode,decode, allocate and deallocate an ASN1 
structure.  With gdb I can
see it stepping through ASN1_item_free, but I don't know why that isn't 
freeing the memory.

Thanks,
