So of course I left out the piece of info that actually caused my problem. At Gemini we're using TDCT to design and build our databases.

http://isacwserv.triumf.ca/epics/tdct/

Turns out this is generating a SUBL field with zeros as shown below. Replacing this field with an empty string solves my problem.

I'll follow up with Rolf to get the rule changed and see if we can (formally?) support aSub in tdct. My symbols are just clones of the genSubRecords used here at Gemini.

#= database generated by tdct V2.17.5

record(aSub,"simpleTest") {

field(DESC,"Array Subroutine Record")

field(SCAN,"Passive")

field(PINI,"NO")

field(PHAS,"0")

field(EVNT,"0")

field(DISV,"1")

field(PREC,"0")

field(LFLG,"IGNORE")

field(EFLG,"ALWAYS")

field(SDIS,"0.0000000000000000e+00")

field(DISS,"NO_ALARM")

field(PRIO,"LOW")

field(FLNK,"0.000000000000000e+00")

field(SUBL,"0.0000000000000000e+00")

On EPICS 3.14.12.7, I have a simple application to test the subroutine in an aSubRecord.
The INAM routine is found, but the SNAM lookup fails. I can't track this down.

1. simple.c, simple.dbd, simple.db, Makefile, and registryDump.txt attached.
2. The aSubRecord fails inside init_record with registryFunctionFind(prec->snam)
3. Yet the registryDump shows both my subroutine names.

Anyone know what I'm doing wrong?

Thanks for your help,
