Hi,

There's something not clear, when you say it doesn't even read one line, do you mean that your application crashes or that the loop is not entered at all ?

Crashes. It successfully passes the

while (!in.atEnd()) {

and crashes on the next line. On Windows, it goes into "Not Responding" then exits.

I tried this:

while (!in.atEnd()) {
            QMessageBox(QMessageBox::Information, "test", "BEFORE",QMessageBox::Ok).exec();
            line = in.readLine();
            QMessageBox(QMessageBox::Information, "test", "AFTER",QMessageBox::Ok).exec();
...

On Windows, I get the BEFORE message, then crash. On Mac and Linux, I get BEFORE and AFTER messages for each line in the script and no crash.

Pretty strange, can you reproduce it with a minimal compilable example ?
By the way, which version of Qt are you using ?

http://sumrandomguy.com/TestReadLine.zip is the project
http://sumrandomguy.com/TestReadLine.exe is the compiled output

Using Qt 5.4

Look like its not, the source link at least causes a 404
