[ 0.6.3 ]  I've run repeatedly --though not often-- in module errors of
that kind:  an interface change at run-time to an open structure makes
a new variable visible in the current package, but the system errors when
it tries to look it up (i.e. when I type in the name):

Error: exception
       wrong-type-argument
       (checked-record-ref '#{Structure 246 #f} '#{Record-type 21 package}

And ,debug finds
'#{Exception-continuation (pc 62) (reinitialize-package! in package-mutation)}

If this isn't known behaviour I will try to reproduce it.  I'm dreaming of
a farm with green ants and glowing potatoes ...
