Summary: Double free or corruption of pointer on failed PW auth

Initial Comment:
I have a perl script that uses libssh2 1.1 (via Net::SSH2) on Linux (RHEL 5 x86_64), and under some conditions, it crashes if it fails to authenticate (bad password) to a host with a glibc error:

*** glibc detected *** conf-sav.pl: fetching newtree/scn/sw1.bhmnoc: double free or corruption (!prev): 0x0000000002394820 ***

If I load it up in gdb with the libssh2 debuginfo installed, I see the crash in session.c at line 843:

        LIBSSH2_FREE(session, session->userauth_list_data);
