This line:
auto lst = capnp::List< capnp::Text>::Builder();
is basically constructing `lst` to be a null pointer. So when you try to
set a value through it, you get an exception (or a segfault).
Try this:
auto lst = context.getResults.initAccounts(1);
lst.set(0, "reza");
(The 1 is the size of the list.)
