下面这个是TCP的槽函数，当tcpSocket监控到有数据时执行下面的函数。现在的情况是当接受到的字符是regsuc或者regfail或者logfail都可以正常运行，当接受到logsucc的时候程序就会崩溃啊！！！
void MainWindow::on_readyReady()
{
char buffer[256];
char *str1;
char regsuc[8]="regsuc";
char regfail[9]="regfail";
char buffer_fail[10]="logfail";
// char buffer_friend[512];
char buffer_log[9]="logsucc";
char buffer_logtemp[8];
tcpSocket->read(buffer,tcpSocket->bytesAvailable());
str1=strtok(buffer,"@");
printf("The buffer is %s\n",buffer);
if(!strcmp(buffer_log,buffer)) {
QMessageBox::information(NULL, tr("提示"), tr("登录成功！"));
}
if(!strcmp(regsuc,buffer)) {
//printf("register success,haha\n");
QMessageBox::information(NULL, tr("提示"), tr("恭喜！用户注册成功！"));
}
if(!strcmp(regfail,buffer)) {
//printf(" register fail,haha\n");
QMessageBox::information(NULL, tr("提示"), tr("很遗憾，该用户名已存在！"));
}
if(!strcmp(buffer_fail,buffer)) {
//printf(" register fail,haha\n");
QMessageBox::information(NULL, tr("提示"), tr("用户名或密码错误！"));
}
}
生成了一个BUG文件，BUG文件的内容如下，请大家看下什么原因呢？
