QFile::open should return false when creating a file with invalid file name on Windows

On Windows, calling QFile::open after constructing a QFile using an invalid file name as path, generates an empty file with a truncated name, and no error is returned on open(). For example: calling QFile::open on testLog-03:20.803Z.txt results in the creation of the file testLog-03 and no content is written with write().

Complete code below:

#include <QFile>
#include <stdio.h>

int main()
{
QString filename = "testLog-03:20.803Z.txt";

QFile file(filename);

printf("Trying to create file %s\n", filename.toStdString().c_str());
printf("QFile.fileName: %s\n", file.fileName().toStdString().c_str());

if (!file.open(QFile::WriteOnly | QFile::Append))

printf("Succeded!\n");

return 0;
}
