Is that the exact error message you are getting? This may be coming from aSubRecord (though with a capital A in the message). Prior to Base 3.14.12.3 aSubRecord had an artificial limit of 10000000 bytes per field. Above this limit the array was not allocated and the field was left as NULL. Which will almost certainly cause a segfault as no code looks for this. https://github.com/epics-base/epics-base/commit/71079ede4b86af81805d0e26d99533909fdba7ba#diff-f2f712a57622c71212a8f9d64c005778L94
