Comment 7 for bug 1580623

I can easily reproduce it on a CCSv5.3b1 (RHEL 6.5) fast controller (= physical machine)
Run a soft IOC with a single ai record, then do caget:

langer @ dain-fc1.codac.iter.org : ~ $ caget ai
ai nan
pure virtual method called

or

langer @ dain-fc1.codac.iter.org : ~ $ caget ai
ai nan
pure virtual method called
terminate called without an active exception
Aborted (core dumped)

Approx 30% of the calls are failing in one of those ways.
