479.1Fix.. NETRIX::&quot;[email protected]&quot;Stephen MooreThu Mar 13 1997 00:0818
Solution...

in file map change the operator[] as follows...

	
	Tref operator[](const key_type& _Kv)
                { _Ty t;
                iterator _P = insert(value_type(_Kv, t)).first;
                return ((*_P).second); }


There appears to be a compiler bug; the orginal code looks OK to me but
just won't work.

Cheers
Steve

results.

Thanks

479.4Alpha-specific problemDECWET::THOMASBug-for-bug compatible with IntelFri Mar 14 1997 15:086
    This problem reproduces on the final Alpha kit, and does not reproduce
    on the final Intel kit.
    
    Thanks for reporting it, and thanks for the workaround.
