So, what I found out until now, that for some reasons in
//pack spd, acc, jrk
no values are stored. However, pose works. So the error message is shown
because I want to access non existing data.
I can print all data in the for-loops and spd[i], acc[i[, and jrk[i]
contain values. I also can access them after storing it in Control2Arm.
They just don't survive serialization and parsing.

Hello,
I have the following Message in my .proto file:
message Control2Arm{
required int32 command = 1;
repeated double pose = 2;
repeated double spd = 3;
repeated double acc = 4;
repeated double jrk = 5;
}
In one class I do this:
Control2Arm c2a;
c2a.set_command(1);
//pack pose
for (int i = 0; i 3; i++) {
for (int j = 0; i 3; i++) {
c2a.add_pose(pose(i, j));
}
}
//pack spd
for (int i = 0; i 3; i++) {
c2a.add_spd(spd[i]);
}
//pack acc
for (int i = 0; i 3; i++) {
c2a.add_acc(acc[i]);
}
//pack jrk
for (int i = 0; i 3; i++) {
c2a.add_jrk(jrk[i]);
}
std::string s;
c2a.SerializeToString(s);
later I parse it:
Control2Arm t;
bool parsed = t.ParseFromArray(_str[0], _str.size());
It works when I don't use repeated in the message and only send one value.
With repeated I get:
[libprotobuf FATAL
/usr/local/include/google/protobuf/repeated_field.h:613] CHECK failed:
(index) (size()):
Is the error in the part I posted?
Thanks a lot.
