Ron Chestnut at SLAC reported that the following record caused the
scan task to crash. I assume that the watchdog restarted the task and
left this record locked - but I don't know. The changes he made to fix
it were worrisome - that is - they did not seem significant. I
will take a look at this - unless someone beats me to it.

BAD:
grecord(calc,"$(Ring):BXBCM:TEMPA") {
field(SCAN,"10 second")
field(CALC,"( (A&C) >> 3 ) - B")
field(INPA,"$(Ring):BXBCM:TEMP.VAL PP MS")
field(INPB,"273.")
field(INPC,"65535")
}
GOOD:
grecord(calc,"$(Ring):BXBCM:TEMPA") {
field(SCAN,"10 second")
field(CALC,"((A&C)>>D)-B")
field(INPA,"$(Ring):BXBCM:TEMP.VAL PP MS")
field(INPB,"273.")
