I know next to nothing about fonts, and I'm sure others will correct me,
but etc/NEWS has the following to say:

  ** 'configure' now warns about building with libXft support.
  libXft is unmaintained, and causes a number of problems with modern
  fonts including but not limited to crashes; support for it may be
  removed in a future version of Emacs.  Please consider using
  Cairo + HarfBuzz instead.

I don't know if it's related (and the 'C-u C-x =' output in your other
message shows the ftcrhb backend in use), but perhaps you can try
building --without-xft to see if it makes any difference.
