Okay, so the dump is definitely way down inside libpam. The next question
is whether it's really libpam's fault, or are we passing it some bad
data. Please install the pam-debuginfo RPM that corresponds to the
pam version you have, and retry --- hopefully that will add a bit more
information to the stack trace.

(The debuginfo-install hint you got might help, though I'm not sure why
it's referencing audit-libs and not pam ... maybe this code isn't
actually in libpam?)
