It's approx. 13MB compressed! If this is repeatable for you, it's recommended that you compile Vinum statically into your kernel, so that you can look at the other symbols in the traceback and obtain source lines for them, as well. It may be that this will be debuggable without that information, but in my experience with similar problems, without a list of arguments to the functions from a live remote debug session and/or a crashdump, the problem is going to have to be found by an engineer eyeballing the call graph and seeing how that particular line could end up with a NULL in bp2 or bp. -- Terry
