pam_tacplus segfaults on debian wheezy 64-bits:

Mar 21 14:34:04 n1 kernel: [84334.929579] sudo[9336]: segfault at 0 ip 00007f80b57c35cb sp 00007fff7f12dfc0 error 4 in pam_tacplus.so[7f80b57bd000+a000]

This is pam_tacplus 1.3.6
I also built 1.3.8 on this system, and it segfaults as well:

Mar 21 15:20:38 n1 kernel: [87123.676143] sudo[10129]: segfault at 0 ip 00007fbf7f54868b sp 00007fff125c2a80 error 4 in pam_tacplus.so[7fbf7f542000+a000]
