Hi Jay:

I found your problem and have attached a patch to fix it. There's a bug in the hex output code which short changes the allocated buffer size by 1. Sort of surprising that it doesn't fallover more often.

I've attached the patch for you to try out.  This will be in 4.3.5 and 4.1-ESV-R14 finals due out at the end of this month.  

Let me know if this fixes the issue for you.

Sincerely,

Thomas Markwalder
