Using \jot crashes \intertext’s spacing

Question

As mentioned in Intertext vertical spacing, there seems to be some inconsistencies in spacing around AMS’ macro \intertext, even without changing the length of \jot. But if I’m using a longer \jot to get mor space between equations in array, the problem gets a real problem.

This is an example showing the problem:

\documentclass[11pt,fleqn,ngerman,DIV=8]{scrartcl}
\usepackage{lmodern}

\usepackage{amsmath}
\setlength{\jot}{2\baselineskip}

\begin{document}
Text Text Text Text Text Text Text Text Text Text Text 
\begin{equation}
    m\cdot a\cdot t\cdot h = 0
\end{equation}
Text Text Text Text Text Text Text Text Text Text Text
\begin{align}
    m &= 0\\
\intertext{Intertext Intertext Intertext Intertext Intertext}
    a &= t\cdot h/2
\end{align}
Text Text Text Text Text Text Text Text Text Text Text
\begin{align}
    (a+b)^2 &\neq \left(a^2+b^2\right)\cdot\left(a^2+b^2\right)\\
    &=\left(a^2+2ab+b^2\right)
\end{align}
\end{document}

Does anybody know how to get exactly the same spacing with \intertext as without it?

Answer 1

I’m sorry … a few minutes after asking I’ve fount the solution via Google: Here one can find a package called amsmath1 which fixes the spacing problem :-)

Shall I send a bug report to AMS?
