longtabu and color compatibility

Question

After last update of TeX Live packages this code won't compile:

\documentclass{article}

\usepackage{longtable,tabu}
\usepackage{color}

\begin{document}

\begin{longtabu} to \linewidth {llX}
    a & b & c\\
\end{longtabu}

\end{document}

I got an error:

Missing } inserted. \end{longtabu}

if I comment out \usepackage{color} everything works. Another strange thing - if I change last column type from X to say l - it also works (even with color package added).

I can reproduce the issue and guess it has to do with recent changes to array.sty, I suspect this is related to https://tex.stackexchange.com/q/466147/35864 — moewe, Jan 07 '19 at 12:12
It seems so. But workaround proposed here (https://tex.stackexchange.com/a/466261/87293) doesn't work in my situation. — andc, Jan 07 '19 at 12:16
Also, it seems my issue is result of 2019-01-05 latex-tools update where issue mentioned by you was fixed. — andc, Jan 07 '19 at 12:34
The fix appears to be incomplete — see https://github.com/tabu-fixed/tabu/issues/1 — but I’ve just submitted a patch that may help us further along, hopefully not breaking anything in the progress ☺ — mirabilos, Feb 24 '19 at 16:29

UPDATE 2019-01-14

An equivalent patch has been applied in tabu 2.9 which has been submitted to ctan.

The following seems to work (I also added the other patch):

\documentclass{article}
\usepackage{longtable}
\usepackage{tabu}
\usepackage{color}
\usepackage{etoolbox}
\makeatletter
\patchcmd\tabu@startpboxmeasure
  {\aftergroup\tabu@endpboxmeasure}
  {\aftergroup\tabu@endpboxmeasure
   \color@begingroup
  }{\typeout{tabu patched}}{\typeout{tabu patch failed!}}
\patchcmd\tabu@LT@startpbox
 {\bgroup}{\bgroup\color@begingroup}
 {\typeout{tabu patched}}{\typeout{tabu patch failed!}}

\makeatletter
\begin{document}
\begin{longtabu} to \linewidth {llX}
    a & b & c\
\end{longtabu}
\end{document}

Is there a way to run this example with an older version of LaTeX as well (e.g. This is pdfTeX, Version 3.14159265-2.6-1.40.19 (MiKTeX 2.9.6840 64-bit))? At the moment it crashes with the mentioned version with a "! Extra }, or forgotten \endgroup." – albert Jan 14 '19 at 12:26
@albert did you ever figure out a way to add this patch only when needed? – Andreas Grapentin Mar 29 '19 at 14:30
@AndreasGrapentin No I didn't try as I want to try to stick to official distributions regarding LaTeX. I think this problem should be tackled on github in github.com/tabu-fixed/tabu and afterwards in CTAN distributions. – albert Mar 29 '19 at 14:49

The new LaTeX3 package tabularray is an alternative to the outdated tabu package:

\documentclass{article}
\usepackage{tabularray}
\usepackage{xcolor}
\begin{document}
\DefTblrTemplate{firsthead}{default}{}
\begin{longtblr}{width=\linewidth,colspec={llX},hlines,row{odd}={blue8},row{even}={azure8}}
 a & b & c \
 d & e & f \
 g & h & i \
 j & k & l \
\end{longtblr}
\end{document}
