Jacek Laskowski 57 Posted December 4, 2020  I don't use Indexer on a daily basis, but I thought I would use it because I wanted to look for many things in the code quickly. I opened its window, indexed the project and started searching. But after hovering the mouse cursor over the name in the indexer window I get AV. This is related to the hint window, as shown in the log.   The error is repetitive, every hovering the cursor generates AV:  [5005FD90]{rtl260.bpl  } System.TObject.InheritsFrom (Line 18239, "System.pas" + 6) + $0 [134F6ABF]{mmx_bds20.dll} VirtualTrees.TBaseVirtualTree.GetDisplayRect (Line 26992, "VirtualTrees.pas" + 40) + $32 [50060298]{rtl260.bpl  } System.TMonitor.CheckOwningThread (Line 19020, "System.pas" + 2) + $0 [5005FDDF]{rtl260.bpl  } System.TObject.Dispatch (Line 18324, "System.pas" + 11) + $0 [50D15292]{vcl260.bpl  } Vcl.Controls.TControl.WndProc (Line 7420, "Vcl.Controls.pas" + 91) + $6 [0EC92198]{CnWizards_D103R.DLL} CnWizNotifier.TCnWizNotifierServices.DoMsgHook$qqrp20System.Classes.TListt1p6HWND__rx24Winapi.Messages.TMessage (Line 1948, "CnWizNotifier.pas" + 1) + $19 [0EC9224B]{CnWizards_D103R.DLL} CnWizNotifier.TCnWizNotifierServices.DoMsgHook$qqrp20System.Classes.TListt1p6HWND__rx24Winapi.Messages.TMessage (Line 1959, "CnWizNotifier.pas" + 12) + $15 [50060079]{rtl260.bpl  } System.@AfterConstruction (Line 18814, "System.pas" + 2) + $5 [50060308]{rtl260.bpl  } System.TMonitor.Destroy (Line 19042, "System.pas" + 0) + $0 [5005F98D]{rtl260.bpl  } System.TObject.CleanupInstance (Line 17680, "System.pas" + 37) + $0 [5005A264]{rtl260.bpl  } System.@FreeMem (Line 4839, "System.pas" + 20) + $0 [5005FBE2]{rtl260.bpl  } System.@IsClass (Line 17942, "System.pas" + 1) + $8 [13542CDE]{mmx_bds20.dll} MMSuperHints.TMMSuperHintWindow.GetObjectHint (Line 164, "MMSuperHints.pas" + 2) + $8 [13542BAD]{mmx_bds20.dll} MMSuperHints.TMMSuperHintWindow.GetHeaderAndDetails (Line 145, "MMSuperHints.pas" + 6) + $E [0EC91F24]{CnWizards_D103R.DLL} CnWizNotifier.TCnWizNotifierServices.AppEventNotify$qqr32Cnwiznotifier.TCnWizAppEventTypepv (Line 1854, "CnWizNotifier.pas" + 16) + $15 [13542A59]{mmx_bds20.dll} MMSuperHints.TMMSuperHintWindow.CalcHintRect (Line 113, "MMSuperHints.pas" + 1) + $10 [50ECE926]{vcl260.bpl  } Vcl.AppEvnts.TMultiCaster.DoShowHint (Line 600, "Vcl.AppEvnts.pas" + 9) + $3 [50E7050C]{vcl260.bpl  } Vcl.Forms.TApplication.ActivateHint (Line 11796, "Vcl.Forms.pas" + 46) + $18 [50E6FF3D]{vcl260.bpl  } Vcl.Forms.TApplication.HintTimerExpired (Line 11552, "Vcl.Forms.pas" + 8) + $4 [50E6C69A]{vcl260.bpl  } Vcl.Forms.HintTimerProc (Line 9191, "Vcl.Forms.pas" + 3) + $5 [50E6EC33]{vcl260.bpl  } Vcl.Forms.TApplication.ProcessMessage (Line 10747, "Vcl.Forms.pas" + 23) + $1 [50E6EC76]{vcl260.bpl  } Vcl.Forms.TApplication.HandleMessage (Line 10777, "Vcl.Forms.pas" + 1) + $4 [50E6EFA9]{vcl260.bpl  } Vcl.Forms.TApplication.Run (Line 10915, "Vcl.Forms.pas" + 26) + $3 [0051D022]{bds.exe   } bds.bds (Line 214, "" + 7) + $7  Share this post Link to post
fjames 0 Posted December 4, 2020 I also got this same behavior after upgrading >=Â v15.0.28. This made the indexer unusable for me. Once I downgraded back to v15.0.27 the indexer worked without AVs again. Share this post Link to post

Once I downgraded back to v15.0.27 the indexer worked without AVs again. Thanks! That is some real valuable information. Â What pops out in the change log between these two versions is the update to a newer VirtualTrees version (7.0 -> 7.4). When I get some time I will try to reproduce that here and track down the cause. 1 Share this post Link to post
Uwe Raabe 2129 Posted December 11, 2020 Unfortunately I am not able to reproduce that here - neither with 10.3.3 nor with 10.4.1. Â Can you reproduce it right from the start or has something to happen before? Share this post Link to post
Uwe Raabe 2129 Posted December 12, 2020 I found a possible cause for the crash, but cannot figure out the condition to make it happen. Nevertheless I changed some code to be prepared for that case and have uploaded a new version. Can you please try if this solves the problem? 2 Share this post Link to post
