| Summary | 0001729: Wrong behaviour when appending vector to vectorField? | ||||
| Description | This code: vectorField test; vector t1(1.0,2.0,3.0); test.append(t1); vector& t2 = test[0]; test.append(t2); Info << "test = " << test << endl; results in the following output: test = 2((1 2 3) (0 2 3)) The first component of the appended vector is not appended correctly. | ||||
| Steps To Reproduce | See code above. | ||||

What happens when you run this in valgrind? Does the behavior change if you use a copy rather than a reference: vector t2 = test[0]; |
|
|
vector t2 = test[0]; results in the expected behaviour: test = 2{(1 2 3)} Have not tried it with valgrind. |
|
|
The issue is that you are holding a reference to an element that will be copied when the list is resized, this is likely to corrupt the memory which valgrind will show. To avoid the problem hold a copy of rather than a reference to the data which will move. |
