Folks,

I have now reproduced the problem with static builds on Linux (Redhat 8)
even with the simple exampleApp that is distributed with EPICS base
(3.14.2).  

I added the following line to exampleApp/configure/CONFIG
STATIC_BUILD=YES

and rebuilt exampleApp.

When I run the application I get the following:
********************************************************
millenia> ../../bin/linux-x86/myexample st.cmd
dbLoadDatabase("../../dbd/myexample.dbd",0,0)
registerRecordDeviceDriver(pdbbase)

dbLoadRecords("../../db/dbExample2.db","user=epicsHost,no=2,scan=2
second")
dbLoadRecords("../../db/dbExample2.db","user=epicsHost,no=3,scan=5
second")
dbLoadRecords("../../db/dbSubExample.db","user=epicsHost")
iocInit()

I then ran the debugger on the resulting core file.

This has now been reproduced on 3 separate Redhat 8 machines.  Andrew
Johnson built on a Redhat 9 machine, and the resulting static binary
worked when run under both Redhat 9 and Redhat 8.  It would be great if
some other folks could try this on Redhat 8 and 9 and see if it is
actually a version problem.  Any ideas why it does not work on Redhat 8
would be most welcome.

Thanks,
Mark Rivers
