Because of further troubles in compiling deMon on the alpha this "summary" comes late.

All replies suggested to find the compilier flag which forces all common blocks to be aligned. On the alpha, this flag is: -align dcommons This helped :-) However, other problems, more specific to the deMon source code appeared and are partly unsolved yet :-( Greetings, Rochus -- ******************************************************************************** Rochus Schmid Technische Universitaet Muenchen Tel. ++49 89 2891 3140 Lehrstuhl f.
