I see this on the test matrix, but I haven't been able to reproduce it

Hmmm - there are a number of tests which trap in sanitizers and in
valgrind. These are artifacts of the tests and not the library. I
think most of these are dangling pointers which result from not deleting
dematerialized data structures via pointers. If I had nothing else to
do, I might go back and fix these tests - but it's a lot bigger job than
meets the eye and I've got other stuff to do.

The changes in this round are of the following
a) miscellaneous trac items fixed.
b) re-enabled codecvt facet which at some point got disabled.
c) modified code to use the standard library implementation of codecvt
if it's available and to use the local boost codecvt implementation
otherwise. This likely explains the difference in results between msvc
d) Enhancement to the test multi-byte characters. This generated errors
which have always been there by have never before been detected. Among
these places is
i) codecvt in some versions of the standard library
ii) codevt in some versions of msvc
iii) visibility attribute in boost codecvt facet
So, I believe that even though we are trapping more bugs, this is a
strict improvement to the previous version.
