Re: possible stack corruption in 2.0.21?

[Steve Powers <sgp@pani.cx>]

I experienced this same issue on the same arcitecture when I upgraded to        
2.0.21 yesterday..                                                              
                                                                                
Reverting to earlier versions of [pam|nss]_ldap : Problem remains.              
                                                                                
Are any other arcitectures experiencing problems with 2.0.21 I wonder? - Guys?
