Has anyone ever seen...
Usage of malloc() in startup file causes tShell to crash
during iocInit on data access violation. Channel access
is still running.
Commenting out of the iocInit call in the startup file and
entering it by hand at the console works, however! The
death of tShell persists even with a taskDelay(600), or
10 seconds, just before the iocInit call so this is not a
timing issue.
This occurs on the following IOC (PPC; EPICS R3.13.5; vxWorks 5.4).
Similar code for a different application runs successfully on
another IOC (same arch and OS) so I suspect it's something local.
Specifically, this
utilsubst = malloc(200)
# kludge
# ulilsubst = "SYS=reallylongname, INST=reallylongname")
sprintf(utilsubst, "SYS=%s, INST=%s", SYS, INST)
dbLoadRecords("../../db/snsUtilEnviron.db",
utilsubst)
causes the following at iocInit:
Starting iocInit
