While my swap method is now working correctly, I have found the the use of modify on a composite_key in order to preform a swap has corrupted the index.
The very next time I attempt to use it in a statement like this:
for (tie(iter,iter_end)=xyIndex.equal_range(make_tuple(i)); iter!=iter_end;++iter)
The for loop runs forever. I also attempted to print the distance(iter,iter_end) and this function never returns.
Note that it happens that the one time my sort function executed, only a single swap was preformed.
Is there a way to fix this?
I lack the context to give a more informed opinion, so the following is mere speculation: take into account that in a expression of the form c.modify(it,f); f is *not* allowed to modify any other element of c except *it. Maybe you are violating this rule in some of your calls to modify()? Joaquín M López Muñoz Telefónica, Investigación y Desarrollo
