qpe运行错误，高手请进阿 [复制链接]

在执行如下语句时
QAbstractServerInterface *interface =
        qtopiaWidget<QAbstractServerInterface>(0, Qt::FramelessWindowHint);
用远程调试出现如下提示
Program received signal SIGSEGV, Segmentation fault.
0x00074030 in QBasicAtomic::init (this=0x0, x=1)
    at /home/jimmy/qt4/qtopia/qtopiacore/target/include/QtCore/../../../qt/src/corelib/thread/qatomic.h:68
68        { atomic = x; }

无调试执行qpe
出现如下
QLine::unitVector: New line does not have unit length                                                    
QLine::unitVector: New line does not have unit length                                                    
QLine::unitVector: New line does not have unit length                                                    
QLine::unitVector: New line does not have unit length                                                    
QPainterPath::cubicTo: Adding point where x or y is NaN, results are undefined                            
QPainterPath::cubicTo: Adding point where x or y is NaN, results are undefined                            
QPainterPath::lineTo: Adding point where x or y is NaN, results are undefined                            
QPainterPath::cubicTo: Adding point where x or y is NaN, results are undefined    

接着跟吧，这样也看不出来。 出现 egmentation fault，绝大部分原因都是访问到空指针。或者在内存位置不是4字节位置的访问。还有很少的情况是内存溢出。
你最好是自己找到那个位置。或者别人碰到类似错误能帮到你。
