PP generates some duff code with multithreading enabled

[Ed Wildgoose]

Please try the following snippet through pp.  It executes fine, but 
crashes when the app exits (at least on win32, havent tried linux yet).  
I would be really grateful if someone could help debug this - it's the 
last major bug standing in the way of packaging my little email app with 
par.

#!/usr/bin/perl
use threads;
use threads::shared;
print "Crashhhh\n";
## fails to exit cleanly after this...
Thanks for any help.

P.S. Autrijus, I will try to check it out myself, but in the latest 
pre-release did you check in Alan Stewarts changes to fix the --icon 
problem where it increases the file size?  I have just been retesting 
his version and it does seem to work fine for me?

Thanks
