Crash (panic) on Windows after a while with an "overflow when subtracting durations" error message #77

Closed gschizas closed 3 months ago

On Windows 11, using latest version (0.8.1), and piping some data to csvlens, I get this error after a while (not immediately, mostly on idle):

The error seems to be overflow when subtracting durations

thread 'main' panicked at /rustc/07dca489ac2d933c78d3c5158e3f43beefeb02ce\library\core\src\time.rs:954:31:

The length of the backtrace varies (the number of 0x7ff78d5e7eb8 actually, the rest are the same). This happens both by reading a file from disk, and from piping data.

EDIT: If it helps, OS Version:

Thanks for reporting! I pushed a potential fix to the main branch, but I don't have access to a Windows machine to reproduce or test this. It would be great if you can check if this still occurs in the main branch.

Closing for now, feel free to reopen if the issue persists.

I wasn't even able to reproduce it on the original build, or on an alternate computer :/ - I guess it's something to do with the number of processors.

Let's just assume it's working, those heisenbugs are the worst!

EDIT: Ok, using the installed (original) version, I was able to reproduce the error, but using the new version I don't see it. So, all good. Of course with these kinds of bugs, you really don't know, but it's good enough for me. Thank you!
