Greetings all,
Here's a strange crash I'm getting using Visual C++ 2013.
I compiled myself Qt 5.2.1 (64bits), "designer" and others work fine,
as well as all the examples and other programs I've tried.
Please consider this code:
--8<-----8<-----8<-----8<-----8<-----8<-----8<-----8<-----8<-----8<---
class S
{
public:
S(QString const& name_):
l_name(name_)
{ }
QString const& name() const { return this->l_name; }
private:
QString l_name;
}; // S
int main(int argc, char* argv[])
{
std::vector<S> vs
{
{"patam"},
{"fo_"},
{"kik_1"},
{"kik_n"},
{"kliton"},
{"wu-harr"}
};
for(S const& l: vs)
{
qDebug() << l.name();
}
return 0;
}
--8<-----8<-----8<-----8<-----8<-----8<-----8<-----8<-----8<-----8<---
Sometimes this code crashes, sometimes it doesn't, in every cases it prints
garbage.
If I replace "QString" by "std::string", it works fine.
If I store directly "QString"s in the vector, it works fine.
If I fill the vector like this:
--8<-----8<-----8<-----8<-----8<-----8<-----8<-----8<-----8<-----8<---
S ts[] =
{
{"patam"},
{"fo_"},
{"kik_1"},
{"kik_n"},
{"kliton"},
{"wu-harr"}
};
std::vector<S> vs;
for(S const& l: ts)
{
vs.emplace_back(l.name());
}
--8<-----8<-----8<-----8<-----8<-----8<-----8<-----8<-----8<-----8<---
...then it works fine.
When trying GCC, either on Linux or using MinGW, it works fine.
Any hint about what may happen? is it a compiler bug, or something else?
Any idea about a workaround?
Thanks in advance for any idea :-)
