[developers] Newer 64-bit builds cause Non-structure argument error

[Stephan Oepen]

hi again, mike,

i just checked in new (32- and 64-bit) LOGON binaries.

the MRS comparison problem you reported was caused
by bogus LNK information (`<>', no content) on predicate
symbols.  it seems this was introduced by a code change
(from february 2012, though the first builds that included
it probably date to mid-may) i had made.  i have changed
the LNK creation to avoid the bogus outputs; i also made
LNK reading more robust, and further wrapped the MRS
comparison calls from [incr tsdb()], to catch conditions
thrown from the [incr tsdb()]-external code.

could you please see whether the latest builds work for
your purposes?  i am about to commit a revision to the
[incr tsdb()] database schema (to better support forest-
based treebanking), and it would be nice to know there
is a functional revision in SVN before releasing a not
fully backwards-compatible change ...

best, oe
