Hi- I'm building a 3.14.6 soft IOC app w/asyn, and the executable segfaults 
in iocInit().  I think I've done everything correctly, but probably missed 
something.  I thought I'd ask here in case it rings a bell...

The startup file: 

	epicsEnvSet(TOP,"/usr/local/cd/soft/ioc/TT00")
	epicsEnvSet(EPICS_BASE,"/usr/local/cd/soft/ioc/R3.14.6")
	epicsEnvSet(ARCH,"solaris-sparc")
	epicsEnvSet(IOC,"iocttk")

	cd ${TOP}

	# Register all support components
	dbLoadDatabase("dbd/ttk.dbd")
	ttk_registerRecordDeviceDriver(pdbbase)

	# tune-tracker DB
	dbLoadTemplate("db/pepii_tt.template")

	# Set up IOC/hardware links -- GPIB/LAN connection
	vxi11Configure("L0", "172.19.53.215", 0, 0.0, "hpib", 0, 0)

	cd ${TOP}
	iocInit()

Boot: 

	############################################################################
	###  EPICS IOC CORE built on Mar  6 2005

	############################################################################
	Starting iocInit
	Segmentation fault

If I remove the "vxi11Configure()" call it doesn't init properly, but also doesn't 
crash:

	iocInit()
  ...
	Starting iocInit

	HB40:X_LIA:AMPL:CTL: init_record : no driver for link 0
  ...
	iocInit: All initialization complete
	epics>

And:

	% gdb bin/ttk core
  ...
	Program terminated with signal 9, Killed.
	Cannot access memory at address 0xff3f8bc0
	#0  0x6aa3c in initRecord ()

Does this point immediately to something obvious?

thanks, 
Mike
