I've added more debugging to rbtree_best_fit.hpp in a fork of interprocess
at github.com, DonOregano/interprocess.git
Direct link to my patched file
https://github.com/DonOregano/interprocess/blob/aba6893976f5be62eed0763c3036013fa3717694/include/boost/interprocess/mem_algo/rbtree_best_fit.hpp

Anyway, among the additions are the checks that I think you wanted above,
that shows that prev_block and next_block are always in the multiset, as
per your email.

I also added logs to every priv_allocate to check that the block that we're
trying to deallocate has in fact been allocated (that it is not just some
random block).

I also print out m_prev_size and m_size, and they're not obviously
corrupted by randomness, they contain 4s and 0s etc, not wierd numbers...
That doesnt really prove anything, though...

I also added a check to make sure that block is not in the multiset, which
it is not.

Just a couple of stupid questions: Are we certain that check() is correct?
And should the invariants hold midway through priv_deallocate? Just so that
I've not inserted checks that are not meant to hold in that place and that
this thing is a red herring?

Below is the output produced by my program, with the logs added, and even
further down (sorry) is the stacktrace from the failed check() call.

*ugh*. What can we do to make this debugging easier? It feels a bit
inefficient...
I could set up a VM on for example Digital Ocean and get everything up and
running, and give you the password and some instructions?

Unless you prefer to do it this way, of course...

Cheers
