I am running swig from svn ;) But I think I have found the bug! There was a bug in the automatic code generation wich will soon be fixed, _and_ this is probably the most crucial, I had to turn off optimization of swig generated code(!?). The problem is that I can't reproduce the error using a small test case. If I could I could commit a bug report. What ever it should work soon.
