Experimental Physics and Industrial Control System
Hello Michael:

>Now with a patch to be tested.
The patch works, thanks so much!
BTW, EDM, also starts PVs by first fetching the metadata.
For historic reasons it does that with only 1 array element because otherwise there were problems with either the CA client or CA server, don't remember.
EDM sources, epics_pv_factory.cc, line 210:
// CA quirk: DBR_CTRL doesn't work with arrays,
// so get only one element:
int stat = ca_array_get_callback(me->value->get_DBR()+DBR_CTRL_STRING,
1u, me->pv_chid,
ca_ctrlinfo_callback, me);
So without this patch, EDM would also crash R3.15.5 IOCs when somebody displays some_record.INP$.
