Hi Hans,

Last night I updated to th elatest beta LMTX (version 2019.10.28 18:57), and noticed that several things don't work as usual. I have not yet been able to find all the examples, but here is one in math:



\sup_{t\in {\Bbb R}}\abs{f(t + T) - f(t)} \leq \epsilon.


The above does not typeset and I have the following error message:

tex error       > tex error on line 7 in file ./bug-math.tex: ! This can't happen (mlist2)

I'm broken. Please show this to someone who can fix me.

Thanks for your attention: OK
PS: the PDF produced now with a colorful « error » is very nice… but the error messages are cryptic :-)
