OK, now we're getting somewhere. The backtrace itself doesn't make a
lot of sense, but the first few line gdb gave after the error point in
the right direction. Sigh! This is yet another in the long and sordid
history of unallocated HtDateTime pointers. I can't for the life of me
understand why Gabriele chose to use HtDateTime _pointers_ instead of
_objects_ in the Transport class, but this has been an endless source
of frustration because half the time they end up being used before the
objects are allocated, and sometimes the pointers get changed without the
objects being properly deleted causing memory leaks.
Anyway, try finding the following line in htdig/ExternalTransport.cc:
_Response->_access_time->SettoNow();
and just before this line, but after the Reset(), add the following line
to allocate the object:
_Response->_access_time = new htDateTime();
Please let us know how it goes.
