Hello

Depending on the indentation amount on the line following a list item,
when (org-insert-item) is evaluated.

Causes Emacs to soft freeze (can be canceled by pressing: C-g)
or an error message is shown: (args-out-of-range 0 1)


Reproduction Steps:

Copy the following lines:
1. a
   b
2. c

(the second line is indented by 3 spaces)

Open a new buffer: C-x b test.org RET
Switch to org mode: M-x org-mode RET
Paste the copied lines: C-y
Move the cursor to the end of the first line, after the: a
(if the cursor is before the a, then the list item is added on a new line above
probably as expected)
Evaluate the following command: S-M-; (org-insert-item) RET

Observed:
The only visible change is that the cursor moves to the beginning of
the "Eval:" prompt in the minibuffer.
The Emacs cpu usage spikes (an infinite loop?)
The soft freeze can be canceled by pressing: C-g
The buffer now shows:
1. a
1.
   b
2. c

The initial example above had three spaces before the: b
The same soft freeze is observed if more spaces are added before the: b
(I only tested it, up to five spaces, but I there might not be an upper limit)

Indented by one or two spaces:
If the initial second line is indented with one or two spaces, then
Emacs shows an error message instead of freezing.
A Backtrace buffer opens with the message:

Debugger entered--Lisp error: (args-out-of-range 0 1)
  replace-match("1. " nil nil nil 1)
  #f(compiled-function (struct old-struct item) #<bytecode
0x497071>)(((1 0 "1. " nil nil nil 6) (6 0 "2. " nil nil nil 13) (16 0
"1. " nil nil nil 20)) ((1 0 "1. " nil nil nil 6) (6 0 "1. " nil nil
nil 13) (16 0 "2. " nil nil nil 20)) 16)
  org-list-struct-apply-struct(((1 0 "1. " nil nil nil 6) (6 0 "2. "
nil nil nil 13) (16 0 "1. " nil nil nil 20)) ((1 0 "1. " nil nil nil
6) (6 0 "1. " nil nil nil 13) (16 0 "2. " nil nil nil 20)))
  org-list-write-struct(((1 0 "1. " nil nil nil 6) (6 0 "2. " nil nil
nil 13) (16 0 "1. " nil nil nil 20)) ((1) (6) (16)))
  org-insert-item()
  eval((org-insert-item) nil)
  eval-expression((org-insert-item) nil nil 127)
  funcall-interactively(eval-expression (org-insert-item) nil nil 127)
  call-interactively(eval-expression nil nil)
  command-execute(eval-expression)


No indentation:
If the indentation is removed from the second line:
1. a
b
2. c

Then it might be working as expected:
1. a
2.
b
2. c

a correctly numbered list item is inserted.

The fourth lines list number: 2. c
didn't change, but it might be expected since there was no indentation
before the: b
therefore it might be assumed that the list ended there.

At least Emacs didn't freeze or show any errors.

Fixed. Thank you.

This is expected. You need to fix the second list manually, with C-c C-c.

I applied the fix manually and there are no more freezes or error messages.

Thank you.
