org-insert-item, indent causes a soft freeze or error message |

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

"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. "

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.
