[Rock-dev] std::vector<bool> allowed in types ?

[Felix Rehrmann]

Hi all,

in Virgo we had the following data structure:

     struct Bumpers
     {
         // Number of Bumpers (specific per Robot)
         int nrFront;
         int nrRear;
         // States of Bumpers. See Aria Documentation and/or ArModes.cpp
         // for an Example how to read out these values.
         int front;
         int rear;

         std::vector<bool> bumpersFront;
         std::vector<bool> bumpersRear;

         base::Time time;
     };

When connecting to a port with this type via orocos.rb a segmentation 
fault happened.
After changing std::vector<bool> to std::vector<int> the segmentation 
fault was gone.

The questions is whether std::vector<bool> is not allowed at all (e.g. 
typelib cannot interpret it correctly,
maybe because the interpretation of bool is not clear) or that this is a 
bug or missing feature?

Thanks
Felix
