[developers] using PET in 64-bit mode

[Francis Bond]

G'day,
2008/8/8 Bernd Kiefer <kiefer at dfki.de>:> PET is compilable on 64 bit machines for quite a while already. I remember> that somebody (i think it was Eric, not quite sure) said that results on 32> bit and 64 bit PET were different for some grammars.>> Maybe the grammar writers could check this by comparing the results of their> 32 bit test runs against the 64 bit PET version. If there are differences,> we can sure pin them down (Peter already has gained some experience with> this lately :-)
Sorry to be so slow to get round to this.
On the same grammar (a fresh download of jacy from svn) on a 1500 itemtest-suite, running on the ubuntu 32bit and 64bit packages there weredifferences in 32 sentences.
How is the best way to report them?

P.S. for example 619 "彼 と は 幼なじみ です" gets 2 parses in 32bit and agenerous 3 in 64bit.  In this case, I believe that three is thecorrect number, at least that is what the lkb gets with the samegrammar.
