While using package gb4e all the dental marks in IPA go berserk

Question

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{tipa}
\usepackage{gb4e}
\usepackage{nomencl}

\begin{document}

\begin{exe}
 \ex

 \gll \noautomath \textipa{\|[to} pani pito\\
 ram.3P.M.Sg. water.F.Sg. drink.PERF.M.Sg.\\
 \trans ram drinks water


\end{exe} 

\end{document}

Answer 1

This is caused by a bug in gb4e that arose after changes to the LaTeX kernel a few years ago. The solution is to add.

\makeatletter
\def\new@fontshape{}
\makeatother

before you load gb4e.

But additionally, you need to load tipa after gb4e since gb4e also defines \|. (Thanks to Ulrike for noticing this.)

Here's a full example.

\documentclass{article}
\usepackage[utf8]{inputenc}


\makeatletter
\def\new@fontshape{}
\makeatother
\usepackage{gb4e}
\noautomath
\usepackage{tipa}
\usepackage{nomencl}

\begin{document}

\begin{exe}
 \ex
 \gll  \textipa{\|[to} pani pito\\
 ram.3P.M.Sg. water.F.Sg. drink.PERF.M.Sg.\\
 \trans ram drinks water
\end{exe} 


\end{document}

Answer 2

To add to the answer by @AlanMunn,

\textipa can use Unicode (via xunicode package), but direct input is easier.

Either way, system fonts can then be used (via fontspec package).

Compile with xelatex or lualatex.
