We've recently introduced a boost multi_index_container into our code base.
Congratulations! Thanks for using Boost.MultiIndex.
Now another seemingly unrelated change triggers an invariant violation in the bmi code during a unit test. [...] Note that the indices use BOOST_MULTI_INDEX_CONST_MEM_FUN on a proxy object, which extracts the indexed value on the proxy-wrapped pointer. It's quite possible our code base makes a change to one of the indexed value without notifying the bmi. Is this something that would trigger an invariant violation?
This is definitely going to break the container's invariants, yes. Key modification has to be done via modify() so as to give the container a chance to reindex elements. So if you are quite sure this is happening try to remove the offending behavior; after this my bet is that the invariant assertion will go away. Otherwise please get back here.
