I'd have to see a test case that exhibits this bug to lay the blame.

Actually, ditroff searches the current font and then all of the
fonts which are marked special (in order) for the special characters.
It could be smarter, and allow S fonts specific to each font, but
it doesn't, at least according to my black box testing.  I tried
making S fonts specific for the B, and I typefaces, but no way
could I convince di-troff to begin its search for the specials
in the first special font that occurs in sequence after the current
font.

The di-troff limit on font size is the minimum of:
	255
	190 (if you have a LaserJet+ and not a II)
	380 - the_total_number_of_special_characters_in_all_fonts

This last limit is likely to be the most limiting, and, as far as
I can tell there is no obvious reason for it.  Current versions
of JetRoff, for example, have around 250 total special characters
defined, limiting the size of a font to 130 characters or so.
If you need more, you have to delete special characters you don't
use to make room for those that you do.

The registered users version of JetRoff contains hands.
It isn't PD, although it is very lowly priced.
