Look for "db.h" files.  You appear to have one hanging around from
version 4.2.52, and that number will appear in the file.  Check
places like /usr/include, /usr/include/db, /usr/include/db4,
/usr/include/db3, etc.  Maybe also /usr/local/include/* directories.

You might also need a compatibility version left on your system,
version 1.85.  Some programs were written to that API, and they try
to include support for that API in later releases as well just so
things don't break.

On this system I see these libraries in /usr/lib/:

  libdb-1.85.so
  libdb-4.3.a
  libdb-4.3.so
  libdb-4.so -> libdb-4.3.so
  libdb.a
  libdb.so -> libdb-4.3.so
  libdb.so.2 -> libdb-1.85.so

Best would be to run it under a debugger, or else set up your system
so that a crash will cause a crashdump file to be written, which can
then be brought up in a debugger to see where the crash occurred.
This won't always catch what we want though.  Your debugger needs to
be thread-aware as Xastir uses multiple threads (and processes too
for that matter).  This is pretty serious developer-type stuff
though, so no biggie if you don't want to head down this path.
