Thank you for trying the new code and providing detailed debugging info. Before we dive into dynamic certificate generation bugs, let's verify that your setup works without dynamic certificate generation. Have you tried running stock Squid 3.1 with SslBump enabled? Does it work? You should be able to surf fine, but should get many certificate mismatch warnings/errors. I believe the SslBump wiki page has the basic config sample. Please confirm that stock SslBump works and we will go from there.
