I get the following error:

! TeX capacity exceeded, sorry [input stack size=5000].
\do #1#2#3->\mathcode `#1
                     ="8000

libpng warning: iCCP: known incorrect sRGB profile

It happened after I started using the semantics package: http://get-software.net/macros/latex/contrib/semantic/semantic.pdf

The document that makes it not compile can be seen here: http://pastebin.com/ycJ6taKw

If I compile with only one of math blocks it will compile just fine, and yes the document is the input to a master .tex file.

Please clarify your specific problem or add additional details to highlight exactly what you need. As it's currently written, it’s hard to tell exactly what you're asking. See the How to Ask page for help clarifying this question. If this question can be reworded to fit the rules in the help center, please edit the question.

  • The presented code is not enough. We have to guess the document class etc. Please post an MWE that we can copy'n'paste and use as is, then it is much more likely that you are going to get help. – daleif May 12 '14 at 11:16

That is hardly minimal, here is a more relevant minimal example (and I will not even start to complain about the structure in the original)

The problem seem to come from the - in the second example. Perhaps a problem from the -> syntax, tough I have (yet) not found anything about it in the manual.

\documentclass{report}
\usepackage{semantic}

\begin{document}

This works 
\[
\mathlig{-><-}{\rightarrow\leftarrow}
\inference[Plus]{a_{1} -> v_{1}\; a_{2} -> v_{2} }{a_{1}+a_{2} ->
  v} \; Where\; v = v_{1} + v_{2}
\]

this does not
\[
\mathlig{-><-}{\rightarrow\leftarrow}
 \inference[Plus]{
   a_{1} -> v_{1}\; 
   a_{2} -> v_{2}
 }{
   a_{1} - a_{2} -> v
 }
 \; 
 Where
 \; 
 v = v_{1} -  v_{2}
\]
\end{document}

Update: Actually if you remove the \mathlig{-><-}{\rightarrow\leftarrow} it compiles just fine, and the -> still give the arrow. So my guess is there is something odd going on in \mathlig.
