 Not that I know of :)
TBH the rate of changes is fairly slow, i.e. the code is mature (some
will call it overripe even !) and while there is bugs, compared to the
size of the system it's relatively small.

  The biggest issue I have is non-linux, I never use Windows or Macs
and I have zero clue that a change there could break the build or else.
There are mingw builds of libxml2 done within Red Hat but that's not
real Windows tests.

  Yes, I also get Coverity Scan reports about it.

  No not that know of

  Sure, the rate of changes is fairly slow though:
    https://git.gnome.org/browse/libxml2/

But getting a report if something breaks on commit there would be appreciated
as long as there is some logic to avoid pestering the list repeatedly with
the same issue. That was a very painful experience on the very early versions
of Coverity for example,
