Christian, Well, it means that the conditions that you described in your original mail are not sufficient to investigate the problem. Setting gdebug=2 should give an indication of where the problem occurs. the wrong version number is not an indication, except that it will be the first victim if something is wrong in the buffer. Try to squeeeze the problem as much as possible. As you know, the response time is in general proportional to the length of the test program ::) Rene Brun Christian Holm Christensen wrote: > > Hi Rene et al, > > On Wed, 22 Aug 2001 10:40:34 +0000 > Rene Brun <Rene.Brun@cern.ch> wrote > concerning "Re: [ROOT] Strange problem with TBranch buffer size": > > Hi Christian, > > > > This type of error occurs when you have a hand-written Streamer and > > a mismatch between the class when writing and reading. > > No streamer was hand written in this case.
