Sorry, but I don't see any evidence of pam's involvement here. The backtrace attached, with no resolved symbols, shows a stack contained entirely within ld.so plus some anonymous mappings. Based on some of the addresses there is *probably* stack corruption as well, but I definitely don't see anything pointing to pam. If you do, please let me know specifically what that is.
