--- Comment #1 from Tomas Mraz <t8m at centrum.cz>  ---
I suppose the buffer_put_cstring that fails is a different one. Most
probably some in the sshpam_thread_conv() function. And that some
module in the PAM stack passes incorrect values to the PAM conversation
function.

in the sshpam_query the only situation where num would be left
uninitialized is when neither of PAM_AUTH_ERR, PAM_ACCT_EXPIRED and
PAM_SUCCESS messages is received and this should not happen due to the
way sshpam_thread() function is written.
