Hi Santiago,

thanks for spotting this.
I can reproduce it.

Patching rsbtest/rsbtest.cpp as
 -\def\mytitle{librsb autotuning benchmark report\\
 +\def\mytitle{librsb autotuning benchmark report\newline
should solve the problem (pdflatex failing to compile LaTeX output).

I'm not fully sure why is \\ not accepted anymore.

Can you confirm this?

Cheers,
Michele
