[ROOT] Warnings using root-files

Hi all,

we are using root 3.01/06 currently. All the branches I'm now talking
about are written without the newly introduced auto evoilution scheme.

We produced one file on an alpha machine. Trying to read it on the alpha
machine results in a warning like the one below and in a seg fault.
Trying to read on a linux machine worked fine without any warning.
Another file produced on another alpha (different compiler version)
worked fine on this alpha machine but with linux I got the same warning
(but without a segfault).

Is this one of the problems which were solved in root 3.02?

Remark: There were _no_ change in the class...

Best regards,
Thomas.

PS: What informations are used for the creation of this checksum?

----------------------------------------------------------------------
WARNING, class:MMcTrig StreamerInfo read from file:test91cof.root
        has the same version:1 than the active class
        but a different checksum.
        You should update the version to ClassDef(MMcTrig,2).
        Do not try to write objects with the current class definition,
        the files will not be readable.
