ScimInputContextPlugin()问题 [复制链接]

我用QT做了一个很简单的东西,编译成功了,但是在我使用这个东西的时候就出现:
[root@kenvix lib]# ./lib
ScimInputContextPlugin()
段错误
[root@kenvix lib]#

有没有人告诉我怎样解决这个问题阿??

这个是在FC5下的，出现了什么问题阿，有没有有人回答阿？？
我很需要这个问题的正确的答案阿

我是在MYSQL数据库的,数据库的简单建立

看上面的代码好像没有问题

#include <qapplication.h>
#include <qdatatable.h>
#include <qlayout.h>
#include <qmessagebox.h>
#include <qpushbutton.h>
#include <qsplitter.h>
#include <qsqldatabase.h>
#include <qsqlselectcursor.h>

#include <cstdlib>
using namespace std;

#include "readerform.h"
#include "bookform.h"
#include "mainform.h"

MainForm::MainForm(QWidget *parent, const char *name)
  : QDialog(parent, name)
{
  setCaption(tr("LibSYS"));

  splitter = new QSplitter(Vertical, this);
QSqlSelectCursor *readerCursor = new QSqlSelectCursor(
            "SELECT DISTINCT rnum, rbnum, rnam, sex, age, rbrwcount, bckcount "
            "FROM reader, loanbook "
            "WHERE reader.rbnum = loanbook.lbnum");
  if (!readerCursor->isActive()) {
    QMessageBox::critical(this, tr("libSYS"),
          tr("The database has not been created.\n"
          "Run the libtable example to create a sample\n "
          "database, then copy library into\n "
          "this directory and restart this application."));
    qApp->quit();
  }
  readerTable = new QDataTable(readerCursor, false, splitter);
  readerTable->addColumn("rnum", tr("Number"));
  readerTable->addColumn("rbnum",tr("Book_name"));
  readerTable->addColumn("rnam", tr("Name"));
  readerTable->addColumn("rbrwcount", tr("Borrowed_count"));
  readerTable->addColumn("bckcount",tr("Returing_count"));
  readerTable->setAutoDelete(true);
  readerTable->refresh();

第一次贴的代码是建立数据库的
是没问题啊
但是在主界面使用按钮的时候,就出问了
主界面的代码是上面的代码

这个问题我自己研究了一段时间了,发现了可能所问题的关键所在,我在gdb和valgrind调试过这个小东东了,显示:
#18 0x08053ff4 in main (argc=Cannot access memory at address 0x1
) at main.cpp:17
这个所用gdb调试发现的,发现内存不能够写入argc的的地址0x1处
但是又使用了valgrind调试程序,又发现了:
==3735== LEAK SUMMARY:
==3735==   definitely lost: 518 bytes in 24 blocks.
==3735==   indirectly lost: 3,168 bytes in 8 blocks.
==3735==     possibly lost: 744 bytes in 6 blocks.
==3735==   still reachable: 1,996,968 bytes in 16,662 blocks.
==3735==       suppressed: 0 bytes in 0 blocks.
段错误

原来是内存的泄漏,呵呵
可惜阿,由于时间的问题,不能够想出一个很好的办法解决这个问题,不知道谁有解决这方面的经验,可以告诉我吗?可以给我一个提示也可以的,呵呵
谢谢指教
