Compilation errors when building latex are not shown

Description :octocat:

Compilation errors when building latex are not shown.

It seems the log is not being parsed or it is malformed somehow. -file-line-error option does not seem to make a difference. Bug is reproducible on a clean spacemacs installation in develop branch with a clean .spacemacs file with latex layer added. I am a new user, so it is likely a misconfiguration on my part. I will appreciate any help with this.

Reproduction guide :beetle:

Start Emacs
Open a tex file with latex layer active. Example tex file:

main.tex
-----------
\documentclass{article}

\title{Foobar}

\begin{document}

\section{foobar}
\label{sec:foobar}

Foobar \phi + 5

\end{document}

Compile with latex/build command (SPC m b)

Observed behaviour: :eyes: :broken_heart : No errors reported, going to next or previous error (SPC m n/N) shows "No more errors", executing TeX-error-overview shows "No error or warning to show". Showing compilation results with C-c C-l shows the following log:

Expected behaviour: :heart: :smile: Errors are shown somehow.
