Invalid patch created about google-diff-match-patch HOT 4 CLOSED

Confirmed.  The issue is the double-negative on this header:
@@ --2,32 +9,36 @@
patch_fromText is absolutely correct to throw an IllegalArgumentException when 
presented with that malformed patch.

Will investigate and push a new version within a few hours.  Thank you!

It looks like a simple indexing failure when moving from one patch to the next. 

Affects all versions of this library.  But I want to run some exhaustive tests 
to 
make sure.  If you are in a hurry, just make the following one line patch into 
patch_make(text1, diffs).  Otherwise I'll post an update with a bunch more unit 
tests 
once I'm completely satisfied that this isn't a case of whack-a-mole.  There 
already 
is one unit test for this, but I can see now it's incorrect.

          if (!patch.diffs.isEmpty()) {
            patch_addContext(patch, prepatch_text);
            patches.add(patch);
            patch = new Patch();
            prepatch_text = postpatch_text;
            // Fixes issue #18:
            char_count1 = char_count2;
          }

Thanks for the update Neil - appreciate the quick response.

Yes, that one line change is a complete fix.  I've pushed out a new version on 
SVN 
and as a source archive which corrects all four language versions.  A new unit 
test 
has been added and an existing test has been corrected.

Thank you for the great bug report.
