my immediate guess is you've got a corrupt amsmath.sty; the line where
your error occurs is miles earlier than where that definition is in my
copy(ies) of amsmath.sty (1996 vs 2101).

there are three commands with parameters defined between the start of
the definition of \math@cr@@@align@measure and (my) line 2101, so
presumably they've been lost in your corruption, too.  they are

\def\fieldlengths@#1{%
    \ifcase\@xp#1\field@lengths\fi
}
\let\maxcolumn@widths\@empty
\def\maxcol@width#1{%
    \ifcase\@xp#1\maxcolumn@widths\fi\relax
}
\def\measure@#1{% ....

that little sequence starts at line 1621: do you have any of those
commands in your amsmath.sty?

i presume you mean "in amsmath"?

not here it doesn't.

same as ever.
