(ITS#5976) seg fault problem starting with version 2.1.14

Full_Name: Allan E. Johannesen
Version: 2.1.15
OS: Red Hat Linux E5
Submission from: (NULL) (

I somehow missed installing 2.1.14, and was still running 2.1.13.  I found that
2.1.15 did not run on one of my servers (but worked on the other 2).  Looking
back, 2.1.14 had the same problem.  2.1.13, compiled and linked again on that
same client still worked ok, so it doesn't appear that libraries went sour.  The
failure is on a gssapi syncrepl client on an opteron.  The gssapi syncrepl
client on Intel works ok.  The master appears to work ok, too.  The ldap server
was running on appliance4 and was accessing the master on appliance1.

When starting it under debugging -d-1, I got to this:

ldap_sasl_interactive_bind_s: user selected: gssapi
ldap_int_sasl_bind: gssapi
ldap_int_sasl_open: host=appliance1.wpi.edu

Program received signal SIGSEGV, Segmentation fault.
