I think I narrowed my problem down a bit. Using thge debugger I found
the line that, as far as I can see, is responsible for the crash, that
is, after these lines a SEGSEGV occurs. 

ADatabaseManager::ADatabaseManager( const char* aDefaultDatabaseName) //
Called with "ALib"
   :  AManager(), // Goes OK
      defaultDatabaseName(aDefaultDatabaseName), // Goes to below (in
bastring.h)
      odbcEnvironment(new AODBCEnvironment), // Is executed
      odbcDatabase(0)
{
	... // Never gets here
}

in bastring.h

177	  basic_string (const charT* s ) 
178	    : dat (nilRep.grab ()) { assign (s); }  

Note: Debugger says: s="ALib"

Than it goes to:

75	    charT* grab () { if (selfish ) return clone (); ++ref ;
return data (); }

Note: Debugger says: selfish = false, ref = 1,

3	    charT* data () { return reinterpret_cast<charT *>(this + 1);
}

SIGSEGV
