Hi I was using package abnt and got the following error:
*TeX capacity exceeded, sorry [parameter stack size=6000]. * * * * \begin{thebibliography}{19}* * * *If you really absolutely need more capacity,* *you can ask a wizard to enlarge me.* I read elsewhere that this kind of error is sometimes due to an open parenthesis in the preamble. However, my preamble is very short and could not find any problem there. When bibliography is removed the output is just fine. Any suggestion of what might be wrong? Beny
