It's looping at this method

This method was removed by commitÂhttp://git.eclipse.org/c/cdt/org.eclipse.cdt.git/commit/?id=0603a4dc4dc6394ef06cdd8d95a4f256fd61dc29. You are apparently not using the latest source.

The variables have changed after your fix though:

this  ÂChangeGenerator Â(id=98)
ast   CPPASTTranslationUnit Â(id=95)
offset Â7023
length Â21450
nodeSelector  ÂASTNodeSelector Â(id=97)
