Donour,

I was not familiar with this "static_buf", but poking around I see that
the generated code for TypeMgrServer (for example in file
powerpc/fullDeb/lib/libc/cobj/tmplTplXTypeMgrServer.I) invokes
    TplMetaTypeMgrServer<INSTNAME> *self = new(static_buf) TplMetaTypeMgrServer<INSTNAME>;
                                                           
and then
    DREFGOBJ(TheTypeMgrRef)->registerTypeHdlr(typeID(), xoh,(uval)self);

This means that method TypeMgr::registerTypeHdlr (in lib/libc/cobj/TypeMgr.C) stores 
the allocated static_buf as "localPtr", which can be retrieved by
method TypeMgr::getTypeLocalPtr (invoked from giveAccessSetClientData
or giveAccessInternal).

What do you have on your generated TplMetaTypeMgrServer.H?

Happy 2007,
