Previous frame inner to this frame(corrupt stack?)

When I run myprogram.exe directly,everything is ok,however,when i debug myprogram.exe
using gdb,gdb reported the following message:

Previous frame inner to this frame (corrupt stack?)

But the myprogram.exe didn't start running from main(),it is impossible that application caused this question.What''s the matter? and "Previous frame inner to this frame (corrupt stack?)" means something wrong certainly?

According to "#77 0x08201cda in typeinfo name for WfDialog ()", I delete the code as below from souece code :
if(m_pWfDialog==NULL)
m_pWfDialog=new CWfDialog(g_pMainFrame);
m_pWfDialog->SetBakWfMsgInfo(wfMsgInfo);
m_pWfDialog->textLabel_Info->setText(strWfMsg);
m_pWfDialog->show();
Then "Previous frame inner to this frame (corrupt stack?)" disappeared!!! Why?
Great thanks to your answer!
