Lookup through the release notes for 6.6.6 I see:

 Fixed a problem where the condor_starter could crash if the job it
 was running used Condor's file transfer mechanism and the full path
 names to the job's files became longer than a few hundred characters.

So I updated to 6.6.8 on Friday and relinked my executables.

Now if the path length is >= 242 and <= 246 it exits with signal 11.
If the path length is >= 247 it goes into the infinite loop.  So the
behavior has changed, but it isn't fixed.
