Description of problem: I encountered an error while building the flint package for Rawhide. The following document is a stripped down version of the problem. It builds without error and produces the expected output on Fedora 24 with texlive-2015-24.20150728_r37987.fc24: \documentclass{article} \usepackage{amsmath,amsthm,amscd,amsfonts,amssymb} \begin{document} $$ 2 \max \left( \left|\frac{a_{n-1}}{a_n}\right|, \left|\frac{a_{n-2}}{a_n}\right|^{\frac{1}{2}}, \dots \left|\frac{a_1}{a_n}\right|^{\frac{1}{n-1}}, \left|\frac{a_0}{2a_n}\right|^{\frac{1}{n}} \right) $$ \end{document} With Rawhide, though, this happens: $ pdflatex test.tex This is pdfTeX, Version 3.14159265-2.6-1.40.17 (TeX Live 2016) (preloaded format=pdflatex) restricted \write18 enabled. ... (/usr/share/texlive/texmf-dist/tex/latex/amsfonts/umsb.fd) ! Argument of \zap@to@space has an extra }. <inserted text> \par l.9 \left |\frac{a_1}{a_n}\right|^{\frac{1}{n-1}}, ? This appears to be a known problem with amsmath 2.15b (the version in Rawhide), which has been fixed in amsmath 2.15d. Is an amsmath upgrade possible? Version-Release number of selected component (if applicable): texlive-amsmath-svn40218-13.fc26.1.noarch How reproducible: Always. Steps to Reproduce: 1. Save the document text show above into a file, say dots.tex 2. Run pdflatex dots.tex in Rawhide Actual results: The error shown above. Expected results: Successful completion. Additional info: See version notes on 2.15d here: https://www.ctan.org/tex-archive/macros/latex/required/amsmath?lang=en
