You can use git bisect to simplify things, but if you don't have a small reproducer for the problem then I don't see how you can avoid doing a full build and install. With a simple reproducer, you can just great using the cc1 or cc1plus binary in the build tree, without installing anything. > > Thanks > > Søren Holm > >
