Wt

I want to add Text to a container, with the HTML Tag <pre>.

I used the following snippet inside a signal handler

auto pre = this->list->addNew<Wt::WText>("Add Sample Text");
pre->setHtmlTagName("pre"); // comment out to make code work

if I do not set HTML Tag name, this works just as expected.
But there is a Segfault in WStringStream if the tag is used.

Then I tried to use a unique_ptr directly, but the same thing happened

auto pre = std::make_unique<Wt::WText>("Some Text to Show Unique Works");
pre->setHtmlTagName("pre"); // same problem, same solution, comment out

this->list->addWidget(std::move(pre));
