[htdig-dev] htdig-3.2.0b4-20020421 sigsegv traceback

[Budd, S. <s....@ic...>]

Hello 
Running htdig-3.2.0b4-20020421  when after several days the following gdb
traceback occurs.
I still have the run in gdb so any questions welcome.

P.S.  Could the snapshot identifier be encoded into the htdig  code so when
there are several around, it is easy to identify which version is being run.
