Re: [l2h] Nesting amsmath constructs align and cases causes infinite loop
I can confirm that this patch does seem to take care of the problem.
Thanks very much for your help.

I find it may be a bug of versions/math.pl. Please apply the
patch below.

Re: [l2h] Nesting amsmath constructs align and cases causes infinite loop
I get the same behavior in my Mac OS environment. The failure is
noted in images.log but not in the console printout:
! Undefined control sequence.
\lthtmlindisplaymathZ -\egroup \centerinlinemath
\lthtmllogmath
\lthtmlsetm...
l.162 \lthtmlindisplaymathZ
I have no idea how it's happening, but images.tex contains a
definition only for \centerinlinemathS:
\def\centerinlinemathS{%
\dimen1=\ifdim\ht\sizebox\dp\sizebox \dp\sizebox\else\ht\sizebox\fi
\advance\dimen1by.5pt \vrule width0pt height\dimen1 depth\dimen1
\dp\sizebox=\dimen1\ht\sizebox=\dimen1\relax}
while latex2html clearly wants to emit the desired definition:
\\def\\centerinlinemath{%\n .
\\dimen1=\\ifdim\\ht\\sizebox\\dp\\sizebox
\\dp\\sizebox\\else\\ht\\sizebox\\fi\n .
\\advance\\dimen1by.5pt \\vrule width0pt height\\dimen1
depth\\dimen1 \n.
\\dp\\sizebox=\\dimen1\\ht\\sizebox=\\dimen1\\relax}\n\n .
Where is that 'S' coming from?!?
