QFile::read/QIODevice::read crashes on big files

QIODevice::read(char*,qint64 maxLen) crashes on large Files if maxlen > qin32_MAX in QIODevicePrivateLinearBuffer::read -> wrong cast of maxlen to int

-------------------------------------------------------------------

QFile tFile("c:/bigfile.bin");

//tFile.size() = 2227814416
if(tFile.open(QIODevice::ReadOnly))

{ tFile.read(tData,tFile.size()); //-> crash }

int read(char* target, int size)

{ !!!!!!!!!!!! size and r is negativ on int cast from int64 > int32 and memcpy crashes int r = qMin(size, len); memcpy(target, first, r); len -= r; first += r; return r; }
