We'll do some more serious testing over the next few days and report back.
Just to close of my branch of the thread, we have done a lot more testing of our application looking for problems with string capacity not being initialised correctly. We found several more failures but they have all turned out to be bugs in our code (typically using fillchar to initialise a record and stamping over the capacity). So from our perspective things look good.
