bug#40323: 28.0.50; error in process filter: Invalid search bound (wrong side of point)

[Jacob Lagares Pozo]

OK, I replaced the old function and now it outputs this:

    ======================================================================
      1 -> (comint-output-filter #<process slack> "[04/20/20,
      12:00:53:017] info: Store: FOREGROUND_APP  
      ")(:comint-pmark nil)
      | 2 -> (set-marker #<marker at 34155 in *slack*>
      34261)(:comint-pmark (#<marker at 34155 in *slack*> .
      #<marker at 34261 in *slack*>))
      | 2 <- set-marker: #<marker at 34261 in
      *slack*>(:comint-pmark (#<marker at 34261 in *slack*> .
      #<marker at 34261 in *slack*>))
      | 2 -> (set-marker #<marker at 34261 in *slack*>
      34316)(:comint-pmark (#<marker at 34261 in *slack*> .
      #<marker at 34261 in *slack*>))
      | 2 <- set-marker: #<marker at 34316 in
      *slack*>(:comint-pmark (#<marker at 34261 in *slack*> .
      #<marker at 34316 in *slack*>))
      | 2 -> (ansi-color-process-output "[04/20/20, 12:00:53:017]
      info: Store: FOREGROUND_APP  
      ")(:comint-pmark (#<marker at 34261 in *slack*> .
      #<marker at 34316 in *slack*>))
      | 2 <- ansi-color-process-output: nil(:comint-pmark
      (#<marker at 34261 in *slack*> . #<marker at 34316 in
      *slack*>))
      | 2 -> (set-marker #<marker (moves after insertion) at 34316
      in *slack*> 34316)(:comint-pmark (#<marker at 34261 in
      *slack*> . #<marker at 34316 in *slack*>))
      | 2 <- set-marker: #<marker (moves after insertion) at 34316
      in *slack*>(:comint-pmark (#<marker at 34261 in *slack*>
      . #<marker at 34316 in *slack*>))
      1 <- comint-output-filter: #<marker (moves after insertion)
      at 34316 in *slack*>(:comint-pmark nil)

I should probably make a simple program that prints a bunch of stuff and then hangs, so I can have predictable and reproducible output, that might help.

So what do you exactly mean by that the process is ending normally?
