I'm running ./fast_repro98.sh on a regular haswell machine with paranoid 
set to "0".

I'll try your patch and see if it makes a difference.

I can also try on a few other machines.  I started setting up a fuzzing 
cluster for this kind of thing but the multiport serial card I got for 
logging the serial consoles crashes fairly quickly under load and I 
haven't had time to track that down.
