  As noted, it's 1.1.x, not 1.x.  But in any case, crashes are bad.

  It's difficult to know what changed from 1.1.3 to 1.1.7 that causes
the problem.  My suggestion, if you're willing to experience, is to
build a version of 1.1.7 with the rlm_ldap module from 1.1.3.


$ rm freeradius-1.1.7/src/modules/rlm_ldap/*
$ cp freeradius-1.1.3/src/modules/rlm_ldap/*
$ cd freeradius-1.1.7
$ ./configure ...
$ make

  Some things in rlm_ldap changed between the two versions.  This test
will let us know if the issue is in rlm_ldap, or elsewhere.

  If it still crashes, tell us.  If it doesn't crash any more, please
tell us, too!

  That doesn't give anything overly suspicious.  Oh well...

  I think I'll have to get a Mac with Leopard, and start using DTrace to
debug these kinds of problems.
