Hi

I am running emacs 29 and org mode 9.6.9

I have set (setq org-latex-line-break-safe "\\\\")

Nevertheless the following example 
#+begin_src 
#+ATTR_LATEX: :environment longtable
| / |  <> |        <> | <>           | <>           | <>           | <>           | <>           |
|---+-----+-----------+--------------+--------------+--------------+--------------+--------------|

|---+-----+-----------+--------------+--------------+--------------+--------------+--------------|
|   |   1 |  12345678 |              |              |              |              |              |
|   |   2 |  12345678 |              |              |              |              |              |
|   |   3 |  12345678 |              |              |              |              |              |
|   |   4 |  12345678 |              |              |              |              |              |
#+end_src

Will be translated to 

#+begin_src 

\begin{longtable}{|r|r|l|l|l|l|l|}
\hline
Num & Documento & \textit{26.04.2024} & \textit{29.04.2024} & \textit{06.05.2024} & \textit{08.05.2024} & \textit{10.05.2024}\\ \hline
\hline
\endfirsthead
\multicolumn{7}{l}{Continued from previous page} \\ \hline[0pt]
\hline

Num & Documento & \textit{26.04.2024} & \textit{29.04.2024} & \textit{06.05.2024} & \textit{08.05.2024} & \textit{10.05.2024} \\ \hline[0pt]

4 & 12345678 &  &  &  &  & \\ \hline
\end{longtable}
#+end_src


#+begin_src 

And this does not compile for TL2023, it gives the following error:
Overfull \hbox (64.42285pt too wide) in alignment at lines 28--32
 [] [] [] [] [] [] [] 
./problem.tex:34: Misplaced \noalign.

                  {\ifnum 0=`}\fi \penalty \@M \futurelet \@let@token \LT@@h...l.34 \hline
           
./problem.tex:35: Misplaced \omit.

                   \@multispan

\multispan ->\omit 
                   \@multispan 
l.39 \endhead
#+end_src
             


The problem are the lines \hline[0pt]

I can query replace them, but is there any other solution.

(defun my-latex-insert-hline-always (row backend info)

This is not what I am seeing with Emacs 29.

Very strange I have not set 
org-export-filter-table-row-functions to nil

But still the above example gets exported as 

\begin{longtable}{|r|r|l|l|l|l|l|}
\hline
Num & Documento & \textit{26.04.2024} & \textit{29.04.2024} & \textit{06.05.2024} & \textit{08.05.2024} & \textit{10.05.2024}\\
\hline
\endfirsthead
\multicolumn{7}{l}{Continued from previous page} \\[0pt]
\hline

Num & Documento & \textit{26.04.2024} & \textit{29.04.2024} & \textit{06.05.2024} & \textit{08.05.2024} & \textit{10.05.2024} \\[0pt]

\hline
\endhead
\hline\multicolumn{7}{r}{Continued on next page} \\
\endfoot
\endlastfoot
\hline
1 & 12345678 &  &  &  &  & \\
2 & 12345678 &  &  &  &  & \\
3 & 12345678 &  &  &  &  & \\
4 & 12345678 &  &  &  &  & \\
\end{longtable}

That compiles with TL2023.

Is this the same result as yours.

In my particular use case (I want \hline always) the solution is 

--8<---------------cut here---------------start------------->8---
(defun my-latex-insert-hline-always (row backend info)
  "Add a hline to every row when exporting to  LaTeX."
  (when (org-export-derived-backend-p backend 'latex)
    (replace-regexp-in-string "\\\\\\\\\\[0pt\\]\\|\\\\\\\\" "\\\\\\\\ \\\\hline" row)))
--8<---------------cut here---------------end--------------->8---

This is the same with what I see (except how timestamps are exported,
but those are not relevant).

I see, so my problem occurs from the fact that I want every endline (\\)
also carry a \hline.

So the solution I posted fixes then this particular problem.
