i have had a look now, and my file is only ~50MB in this case, so this bug
should be no problem.
besides, i am running on 5.6.3, as i haven't a previous version installed
currently.

my code was:
qint64 res = f.write(data);
with data.size() == 51489714
and res == 33554432
the only possible issue i see is with the 2nd if here in qint64
QFSFileEnginePrivate::nativeWrite(const char *data, qint64 len)
if (!WriteFile(fileHandle, data + totalWritten, currentBlockSize,
&bytesWritten, NULL)) {
if (totalWritten == 0) {
// Note: Only return error if the first WriteFile failed.
q->setError(QFile::WriteError, qt_error_string());
return -1;
}
break;
}
i think it "silently" breaks here without setting error condition on the QFile
when hitting errors
on all chunks but the first one, thus returning a size lower the input array
size, which is the behaviour i see.
