[rjmholt]

@PrzemyslawKlys do you have a small reproducible scenario at all? What were doing when the crash happened?

[PrzemyslawKlys]

Unfortunately it doesn't happen a lot. It happend 3 times so far in 2 days.

I believe in last case it just happend. I was typing something in VSCode, maybe doing CTRL C+V and it simply crashed.

But it as well cane be related to those 2 things:

• i frequently use CTRL + S and I have format on Save - I don't think I did this this time thou
• i use onedrive to store my files (as additional safe to github commits) so things may trigger weird results

[rjmholt]

Understood.

I'm pretty certain it's a race condition.

I'll need to look into it as part of broader work on the extension (getting threading right generally), so the fix is unlikely to be simple or immediate.

Was just editing some code. Stopped, was looking at something else and noticed it crashed.

Let me know if you want me to keep on adding as i encounter those or it's enough for now (maybe you need full log as well). I guess without reproducible case it's not gonna be easy/nessecary. One more thing that I do common is having 3+ VS Code windows with 3 different projects open at all times.

[rjmholt]

This information seems like enough to go on for now -- it looks like the file offset in VSCode is not synchronised with the actual file.

It's the kind of thing that may be difficult to implement correctly, but we should still catch the error and just move on.

[csandfeld]

I am experiencing what I believe to be the same issue, several times a day.
I think the problem first occured after the powershell extension was updated to version 1.8.3 (however that may be coincidental).

Let me know if you want me to try reproducing with verbose logging enabled.

[rjmholt]

Hi @csandfeld, I think the logging has identified where in the code the issue is, but won't help us identify why.

Can you describe anything about how you were modifying the script when the extension crashed?

[csandfeld]

Hi @rjmholt

I ran into this issue several times today, while testing some enums, classes, functions, and C# code (with Add-Type). I loaded a file holding the enums and classes, and a number of files each holding a function, into the active session using F5 (so running the debugger, but without doing any actual debugging). Then while typing a variable name ($whatever) in some test code, it would crash. Did that several times in a row.

[rjmholt]

The variable name was at the end of the file right? Was the file a new untitled file? Or a modification of one changed on the filesystem?
