[etherlab-users] Default Trap Handler: vector 14: Suspend RT task

[Dr.-Ing. Wilhelm Hagemeister]

Hallo Mr. Kotlarski,

i have had "Trap vector: 14" with a Simulink Modell ones when I tried to 
access a vector-variable out of it's bounds.  This can e.g. happen with 
the Simulink-"Selector" Block and external element indices.

Divison by zero usually gets handled by the generated code from RTW.

Kind regards,

Wilhelm Hagemeister.
