Experimental Physics and Industrial Control System

Note that the setup of my original system was:
vxWorks:
Using the same 3.14.8.2. (optimized) client, the faulty behaviour (100%)
appears with 3.14.9 (optimized) IOCs, and does not appear with 3.14.8.2
(optimized) IOCs.
Linux:
Using the same 3.14.8.2 (optimized) client, the faulty behaviour (20%)
appears with a 3.14.9 (optimized) soft IOC, and does not appear with a
3.14.8.2 (optimized) soft IOC.

More observations from Steven:
Now, I just rebuilt all of base on linux with HOST_OPT=NO. Even stranger.
Using optimized build on linux, caget failed with an unexpected read
access error 19 out of 20 times just tested. Using non-optimized build
on linux, caget failed 2 out of 20 times!
This appears to be a major hint. I need to confirm that the behavior changed
this way (as described above) when the CA client library's optimization
level changes, and that during this experiment the IOC's optimization level
was not changed.
