Hi Giovanni,
Thanks for reporting the bug. I've tried to apply the patch you provided
but then it fails to build with the current unstable dependencies.
Having a look at upstream I've found a commit [0] that seems to fix this
bug and I've added it as a quilt patch in the "boost-fix" branch [1].
Anyway, I prefer to test it a bit more before merging it into master and
uploading a new release.
