我試圖從內存轉儲中使用Konica Minolta PCL驅動程序查找訪問衝突的原因。我會盡量根據需要提供儘可能多的信息。也許其他處於類似情況的人會從中受益。如何從轉儲中分析打印機驅動程序中的崩潰
我正在調查的軟件是在Delphi 2007中通過COM託管.NET組件的非託管窗口的組合。其他崩潰轉儲表明可能的連接在設置浮點異常時出現錯誤http://connect.microsoft.com/VisualStudio/feedback/details/535285/using-events-on-interop-assemblies-causes-system-stackoverflowexception#details，我試圖確定是否有任何相似之處。
轉儲創建造成了第二次機會異常：KOAZ8J_O OAPIGetPrinterEncryptionSettingForDriver + 36778在C：！\ Windows \ System32下\閥芯\ DRIVERS \ W32X86 \ 3 \ KOAZ8J_O.DLL造成的訪問衝突異常（0000005）試圖從存儲器位置0x1906ef0c上線程讀取16

是否有人能夠發現此彙編代碼中的任何明顯錯誤？爲什麼它會處理這個無效的內存位置。我還在尋找有關如何進一步查明錯誤的指導。我的目標是尋找一種解決方法（因此不會運行此代碼塊）並向驅動程序的作者提供儘可能多的信息。
