2.10.10 works on one machine, but not on another (St9exception)

[Ed Stauff]

I'm developing a web app using LilyPond, and version 2.10.10 is behaving 
differently on my production server than it does on my development 
server.  It seems to work fine on my development server, but on my 
production server I get errors like this:

In the last example, when I when I tried it again without the "--png", 
it ran without errors.

My development server (where it works) is running Windows 2000.
My production server (where it doesn't work) is running Windows Server 
2003.  (And please don't tell me to change my OS.)

Anybody have any idea what's going on?  I double-checked that both 
servers are running LilyPond 2.10.20.  I didn't have this problem with 
the previous version I was using, 2.8.8.

Are there prerequisites or dependencies I should check?

What does a LilyPond return code of 128 mean?  Shouldn't the return 
codes be documented somewhere?  I couldn't find them.

Does anyone know what an St9exception is?  I've searched the web in vain.

Thanks,
