A bug somewhere which needs to be killed.

If this is a Linux/glibc based system you can try the following which
should allow identifying the bug:

Set the envirnoment variable MALLOC_CHECK_ to 2 while running Squid
under gdb. Should trap the error.

  gdb /path/to/sbin/squid
  set env MALLOC_CHECK_ = 2
  handle SIGPIPE pass noprint nostop
  run -DNYCd3
  [wait for crash/alert]
  backtrace


but it could also be a bug in ldap_auth..

Btw, why are you using ldap_auth instead of the official squid_ldap_auth
distributed with Squid?

Henrik
