I took a look at this issue, but was unable to reproduce it myself.
Even with a testcase provided by Mark, I still was not running into
invalid memory access errors.

Anyway, I created a patch that should avoid such issues by reference
counting the credential handle and only allowing it to be freed if
it's not needed anymore.

Please take a look at the attached patch and tell me if it fixes the
problem for you. Thanks.

Best regards,
Marc
