BTW, this is actually the xdvipdfmx driver that's crashing, rather  
than xetex itself....

....which is why these lines still appeared. (xetex didn't notice  
that the driver crashed, as it had already sent all its output down  
the pipe.)

I tried a small sample with this font on Mac OS X (PowerPC) and Linux  
(i386), and didn't get a segfault on either of these; the output  
looked OK (modulo the limited character set of the "tryout" font).

It may well be that the font is poor quality; that's true of many of  
the cheap or free TrueType fonts out there that were made with cheap  
or free tools. Apple's ftxvalidator utility does report several  
errors, though obviously the font is still able to work in many  

Another possibility is that xdvipdfmx has a bug that's leading to a  
crash with this font. (Well, even if the font is faulty, segfaulting  
is not a good response!) I'll try to investigate further, on another  
system or two. Does OpenBSD create a log/dump of some kind that shows  
a backtrace for the crash? Or can you run xdvipdfmx under gdb and  
generate one? To do this, you'd run "xelatex -no-pdf test", so it  
creates a file test.xdv on disk; then load xdvipdfmx under gdb, and  
run it with the command line "-E test.xdv".
