Any ideas where this black magic comes from ?
From what I know Symbols always end up in the out-pointers because they are always referenced at least from the Symbol table.
Not necessarily. The symbol table is a *weak* set and hence if you don't strongly hold onto the symbols they get into the segment array and not into the out pointers! This is a potential source of subtle problems because after loading the segment you end up with duplicated symbols (we run into this with Cmsbox...). The easiest solution is to create a temporary variable and assign "Symbol allSymbols" while creating a segment.
That means they are serialized by the reference stream, which means that the not so black magic happens in ReferenceStream>>#readSymbol.
Yep. Cheers, Adrian
