Inserting Data to a temporary table

Question

Hi,
This may sound strange, but I see code that inserts data to a temporary table, which sources from the same temporary table. The code looks like this:
-- Some code that initially inserts data to #tmpA
IF(UserId = 0)
BEGIN
INSERT INTO #tmpA
SELECT * from #tmpA
END
I'm just curious on how this code snippets would do. Would this end up to an infinite loop? The whole code runs endlessly, I don't know if it's because of the CURSOR that is being implemented, or is it because of this code snippets which probably inserts data
to #tmpA endlessly?

Hi KEARPEE,
The code is really long, so I just emphasize on the area where I'm concern with.. it's something like that:
-- Some code that declares variables. Some code that initially inserts data to #tmpA
IF(@UserId = 0)
BEGIN
INSERT INTO #tmpA
SELECT * from #tmpA
END
-- Some code that updates the temporary table, and display the result of the temporary table
