I'm using the C# version of the code. I get a 'System.OutOfMemoryException'  
with the two attached files. Note that these files are not similar at all, 
apart from being XML files, and the one is very large. The exception occurs in:

   protected List<Diff> diff_map(string text1, string text2)

This is the code I use to call it:

var dmp = new DiffMatchPatch.diff_match_patch();
dmp.Diff_Timeout = 0;
dmp.Diff_EditCost = 4;
dmp.Match_Threshold = 0.5F;
var diffs = dmp.diff_main(text1, text2, true);

Merged into: #26

Attachments:

Yes, both the speed and the memory footprint are concerns. They are constantly being improved, but this will be a never-ending process (until it can diff infinitely large files in zero time and 0 bytes). Merging with the existing performance bug.
