OK, I think the attached file is pretty much minimal, and it seems to
reproduce the problem consistently.  It's possible that the crash happens
when a character inside the \urdu{...} is not present in the Urdu font; at
least I see a '!' in there, and when I delete that, I get a warning msg in
place of a crash.

% There are two Nasta'liq fonts that we have tried, and each has its advantages;
% uncomment whichever \newfontface command.
% The first is CRULP's Urdu Nastaliq, version 1.02, downloaded from
% http://www.crulp.org/software/localization/Fonts/nafeesNastaleeq.html.
% This causes CMap to complain about "Invalid CMap mapping entry."  But it

% (Trying to specify 'Language=Urdu' doesn't work: Nafees doesn't list that.)
% ...and the second is the Alvi Nastaleeq font, downloaded from
% http://alvi.urdushare.net/blog/200811/download-alvi-nastaleeq/
% At least one observer reports that this is not quite as pretty as the Nafees
% font, but it does place the tashdeed diacritic correctly (whereas the Nafees
% font tends to place it below or in the middle of the base character).

\newfontface\urdufont[Script=Arabic,Scale=1.2]{Alvi Nastaleeq}
% Specifying 'Language=Urdu' for the Alvi font gives a warning that the font does
% not contain language 'Urdu' for script 'Latin'.  Probably harmless, but specifying
% Urdu does not seem to make any difference, perhaps because the font is only
% made for Urdu.

Here are some Urdu words: \urdu{بیٹا! مجھے روز فون کیا کرو}
