      I’m struggling with a strange crash that is somehow unique.

      Having said this, I’m not able to replicate running the debug version in VS Studio Debugger.
      In addition, a new portable download does not seem to be affected as well. (was using dark and light mode for testing)
      .
      The only way I’ve found so far is to create a production version with debug symbols, then I can force the crash relatively easily.

      So my conclusion is that this is somehow related to my work environment, but as I said, plugins are not involved.

        Of course, I had an idea immediately after posting.
        Since it crashes in an XML-related function, you could try removing these files one by one and see if that fixes the problem.
        And indeed, I couldn’t reproduce the problem after creating a new config.xml.
        Let’s try to find out what caused this in the old xml. If that was indeed the reason.

          Found something.

          Downloaded the new portable version.
          and opened the config.xml file in another editor and changed
          useFindSettings="no" from the SmartHighLight node to useFindSettings="yes".

          Now the same crash occurs.
          Can someone please confirm this?
          Thank you.

            Hello,

            I’m also able to crash the Notepad++ 8.8.6 in similar circonstances.

            I’m not an expert debugger like you seem to be, but here is the crash report I get from Windows :

            Signature du problème :
  Nom d’événement de problème:	BEX
  Nom de l’application:	notepad++.exe
  Version de l’application:	8.8.6.0
  Horodatage de l’application:	00000000
  Nom du module par défaut:	StackHash_2fd1
  Version du module par défaut:	0.0.0.0
  Horodateur du module par défaut:	00000000
  Décalage de l’exception:	0040df98
  Code de l’exception:	c0000005
  Données d’exception:	00000008

            I can see the code c0000005 which is common with you.

            I can produce the crash without link, just with ctrl+click fastly in an empty file.
            And can also produce a crash with alt+click and moving my cursor.

            This happens only if I build myself from the code (with no modification) from Notepad++ github source, in 8.8.6.

            I can’t reproduce if I download directly a 8.8.6 build from Notepad++. I also can’t reproduce if I build myself from 8.8.5 source.

            I discovered that disabling Smart Highlighting (which works perfectly) prevent the crash and I can alt+click or ctrl+click without crash.

              Thank you very much—I am currently away on family business. I will continue working on it later if no one has found a solution by then.

                  I recompiled with your code modification and I can’t crash Notepad++ anymore ! :)

                  So I can confirm your modification fixes the issue on my side. Thank you !
