Follow-up Comment #1, bug #625 (project tex4ht): I have now a workaround. So able to build my output.
I changed my program to check the length of each Latex equation generated by Maple before writing them to the latex file. If each equation (as string) has length > 10,000 then will not write the whole Latex generated for that part. I did not know what is the limit for tex4ht, so picked 10,000. I found the equation that was causing this bad register code was over 300,000 length. I know the latex generated by Maple could be better, but that is how it is generated now. So I am OK for now. But it will good to know why tex4ht generates this error and not lualatex. Luckily, there are not too many such cases where such huge equations are generated. --Nasser _______________________________________________________ Reply to this item at: <http://puszcza.gnu.org.ua/bugs/?625> _______________________________________________ Message sent via/by Puszcza http://puszcza.gnu.org.ua/
