Description lihuiibm 2010-05-14 03:18:18 UTC 
Dll call causes OOo crash sometime, such as: Call HtmlHelp(0, "C:\Test.chm", 0, 0):
Public Declare Function HtmlHelp Lib "hhctrl.ocx" Alias "HtmlHelpA" _
         (ByVal hwndCaller As Long, ByVal pszFile As String, _
         ByVal uCommand As Long, ByVal dwData As Long) As Long
Sub windowsAPI()
  Call HtmlHelp(0, "C:\test.chm", 0, 0)
End Sub

I tried to delete the line "FreeDllHandle( pDll->GetHandle() )" in method
"SbiDllMgr::~SbiDllMgr()" and "void SbiDllMgr::FreeDll( const ByteString&
rDllName )", OOo did not crash, so I think the cause may be:
The dll call is not completed(The dll call is async?), but the dll is free.

Known the root cause and has a rough fix.
