Dirk,  I was seeing something similar (though in 3.14.11),
and "dbpr <recordname>,5" showed "DTYP: <nil>",
until I added the line
device(aao,CONSTANT,devAaoSoft,"Soft Channel")
to the .dbd file.

Hi all,
When an aao is written by an other record, the ioc crashes. The
problem seems to independent of the DTYP of the aao. I used an
(unofficial) Soft Channel support (attached).
Example db:
record (aao, "aao1")
{
    field (FTVL, "DOUBLE")
    field (NELM, "10")
    field (OUT,  "aao2")
}
record (aao, "aao2")
{
    field (FTVL, "DOUBLE")
    field (NELM, "10")
}
record (ao, "ao1")
{
    field (OUT,  "aao2")
}
When I write aao1 or ao1 the IOC crashes. (Note that aao2 is not even
processed in that case.) If I write directly into aao2 there is no
problem.
Any idea?
I am using EPICS R3.14.8.2.

Dirk
