Thanks.

Can you show a full backtrace with one of the problematic fonts
(i.e. "bt full" command in GDB), from the crash location?  The
backtrace you posted originally shows only the names of the functions,
it doesn't even show line numbers, let alone arguments to the
functions.  You also didn't say which Emacs version is that (it will
become important if you post a more detailed backtrace).
