        internalSymbols.put(symbol.name, symbol);
        if (shadowingSymbols == null)
            shadowingSymbols = new HashMap<String,Symbol>();
-->        Debug.assertTrue(shadowingSymbols.get(symbolName) == null);
        shadowingSymbols.put(symbolName, symbol);

This seems to be where I'm calling shadowing import. However a small
file with just this doesn't trigger the bug, nor does it seem to
happen on all loads.

(defpackage "ENCAPSULATE" (:USE "CL" "SYSTEM")
	    (:export "TRACE" "UNTRACE" "ADVISE" "UNADVISE" "ARGLIST"))
(in-package encapsulate)
(shadowing-import '(trace untrace advise unadvise arglist) 'cl-user)
