Hi,

excas serves out a number of channels, such as jane, fred, etc.

I created an alh config file that uses these, than ran alh. excas

complains, and alh gets a segmentation fault. Below are outputs, alh

config file, and gdb output.

Output from excas:

$ excas
filename="../../../include/gddAppFuncTable.h" line number=263
application type unregistered - ukn appl type code = 19

filename="../../../../src/cas/generic/casStrmClient.cc" line number=849
application type unregistered - in monitor response

Output from alh:

$ alh -debug
no XML!
programName=alh

OpMod File is ALH-default.alhOpmod

Filename is ALH-default.alhOpmod

AlarmLog File is ALH-default.alhAlarm

Filename is ALH-default.alhAlarm

Config File is ALH-default.alhConfig

Filename is ALH-default.alhConfig

fileSetupCallback: filename is

/group/da/dist/epics-3.14.10/base/testApp/excasTest.alhConfig

Filename is /group/da/dist/epics-3.14.10/base/testApp/excasTest.alhConfig
Segmentation fault (core dumped)

alh config file:
