Memory leak in new C++ version #40

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
I haven't tried the new version yet, but this looks, to me, like it leaks:

380:  int *v1 = new int[v_length];
381:  int *v2 = new int[v_length];

<http://code.google.com/p/google-diff-match-patch/source/browse/trunk/cpp/diff_m
atch_patch.cpp?spec=svn85&r=85#380>

I don't see any `delete [] v1;` or `delete [] v2;`.
After all this is only C++ ... no garbage collectors here ;-).

Good catch.  Thanks.  A pair of deletes need to be added at all three exit 
points in that function.  I've checked the rest of the codebase and this bug 
appears to be unique.

The change has been sent for code review and will likely be pushed on Monday.

Fixed and uploaded to both Subversion and the downloadable package.

Thanks for catching this!
