Description:	tktest90 crashes on exit (I think). Narrowed it down to winClipboard.test (or at least this file by itself triggers the crash unlike other test files). Anyone testing will likely need to enable the JIT debugger on Windows else you will not notice the crash. Alternatively, check the Windows Application log where the crash is reported. My VS Studio debugger reports it cannot determine crash location because the unhandled exception is .NET 4.0 and the debugger only supports 2.0. I don't even know where .NET enters the picture (does Tk use any UI features from .NET) ? Also happens with wish90.

Thanks! oehhar added on 2024-07-26 16:51:31: The error code "5" is an invalid memory access. This may be caused by the code line: winPtr->mainPtr->winPtr with winPtr beeing a NULL pointer. So, this also indicates, that the fix is effective. I would just merge this, it is great ! Harald oehhar added on 2024-07-26 15:23:25: Hi Ashok ! Great work ! My recipe to reproduce: start MS-VS 2015 x86 prompt compile TCL 9.0b3rc0 and Tk9.0b3rc0 by "cd win; nmake -f Makefile.vc release" start test in tk win folder by: "nmake -f makefile.vc test TCLDIR=c:\test\tcl9.0b3\tcl9.0b3 TESTFLAGS="-file winClipboard.test". For me, there are 8 passed tests and no failures. Go to Windows Start button. Search "Event Viewer" -> German Windows finds "Ereignisanzeige" -> start it Go to "Windows protocols -> Application" A crash is shown with the following text: Name der fehlerhaften Anwendung: tktest90.exe, Version: 9.0.1.3, Zeitstempel: 0x66a35c1a Name des fehlerhaften Moduls: tcl9tk90.dll, Version: 9.0.1.3, Zeitstempel: 0x66a35b24 Ausnahmecode: 0xc0000005 Fehleroffset: 0x00024879 ID des fehlerhaften Prozesses: 0x630 Startzeit der fehlerhaften Anwendung: 0x01dadf6df9204d0a Pfad der fehlerhaften Anwendung: C:\test\tcl9.0b3\tk9.0b3\win\Release_VC1900\tktest90.exe Pfad des fehlerhaften Moduls: C:\test\tcl9.0b3\tk9.0b3\win\Release_VC1900\tcl9tk90.dll Berichtskennung: cf9f380c-c6e3-4993-b679-f4c66e948f94 Vollständiger Name des fehlerhaften Pakets: Anwendungs-ID, die relativ zum fehlerhaften Paket ist: Whenn adding the fix to tk, the error log entry is gone. Great work ! Harald apnadkarni added on 2024-07-26 14:56:26: Proposed fix in [cc07c7a2]. Needs review.
