I've hit a bug that I cannot fix (no warnings/errors in the logs).
Here is a mwe:
documentclassarticle
usepackage[english,french]babel
usepackagebreqn
begindocument
[A, B, C]
selectlanguagefrench
[A, B, C]
selectlanguageenglish
[A, B, C]
enddocument
I use the following command to compile:
$ latexmk -lualatex bug.tex
The output is as follows, the commas are mapped to a Gamma symbol !?

Does anyone have a clue on how to fix this ?
$ lualatex --version
This is LuaTeX, Version 1.07.0 (TeX Live 2018)
$ latexmk --version

The babel-french module does std@math@comma upon entering and also exiting French language blocks.
This resets the mathcode for the comma to the standard, but breqn wants that the mathcode stays "8000.
Simply make std@math@comma to do nothing.

You should be aware that breqn is not really compatible with several package and is better not used in serious typesetting tasks.
Great investigation egreg, many thanks for the detailed explanations !
