PAM issue related to ix86 machin

[jkwagh]

Hi All,

I am using pam-0.90 to autheticate the webs service. It's working fine
with all architecture other than ix386. Problem is when I tried to
authenticate the user with wrong password, my webs server got killed
due to seg-fault(only when compiled for x386 architecture). Following
is the backstrace where does it crashes.

Program received signal SIGSEGV, Segmentation fault.
[Switching to Thread 1024 (LWP 7858)]
0xb7e6f44c in _unix_verify_password () from /lib/pam_unix.so

If I autheticate for correct user then it's working fine.
Can anybody help me for same?
Thanks in advance.

line number 119 is screwing things up.
double check what is getting passed to authHandler.

Thanks

Better ask in a newsgroup more appropriate to PAM and/or your platform.
This is not a query about standard C.
