I tried to reproduce this on my machine, but couldn't.  What I see is
that the chain of calls you reported happens only once, when the first
frame is created.  When I later create a second frame, either with
"C-x 5 f" or by invoking emacsclient, x_new_font is indeed invoked
again, but it doesn't call Fset_char_table_range, and consequently no
additional sub-char-tables are allocated.

So I guess your customizations, in particular those related to fonts
and fontsets, are critical for debugging this problem.

Thanks.
