Traceback / crash with infotag get leg_state

If no argument is given to the command "infotag get leg_state" there no error from TCL/IVR, but align errors. Also the router can crash but could not reproduce, if I can will post more info here.

Can be reproduced with the minimum script

proc actHandoff {} {puts [infotag get leg_state]}

set fsm(INIT,ev_handoff) {actHandoff same_state}

fsm define fsm INIT

Hi,

Did you try to pass legId, do you have any issues.

set legState [infotag get leg_state $legID]

Thanks,

Raghavendra

Did you try to pass legId, do you have any issues.

Please understand the point I'm trying to make:

Incorrect usage of TCL/IVR statements (missing mandatory parameter in this case), normally causes an error from the subsystem. Not tracebacks and certainly not crashes.

I understand your issue, thanks for the info. I will forward it to Dev Team.

Thanks,

Raghavendra

Thank you. Attached crashinfo file.
