QByteArray::resize throws std::bad:alloc if asked to allocate std::numeric_limits<int>::max()

The following code

#include <QByteArray>
#include <QDebug>

int main(int argc, char *argv[])

{     QByteArray ba;     ba.resize(std::numeric_limits<int>::max());     qDebug() << ba.size(); }

 

crashes with

terminate called after throwing an instance of 'std::bad_alloc'
what(): std::bad_alloc

 

I've been told "it is known" that the max size QByteArray can hold is 2^31 but i can't find anything in the documentation.

 

It would be nice if one could have a QByteArray::maxsize or something that could be used for that.
