Crash when using certain symbols

[marvinborner]

While scrolling through my thesis the preview window always crashes at the same parts of the LaTeX code.

I could narrow it down to my use of \twoheadsquigarrow (as defined in this stackexchange post).

Some observations for the reproduction file below:

• texpresso-tonic file.tex compiles the PDF without problems
• latexmk file.tex compiles the PDF without problems
• texpresso file.tex crashes immediately (or, if on a separate page, when the arrow would be visible)
• \rightsquigarrow without two heads works fine (therefore it's probably not a font problem)

A minimal reproduction (taken from the stackexchange post):

\documentclass{article}

\usepackage{amssymb}
\usepackage{trimclip}

\makeatletter
\newcommand*{\twoheadrightsquigarrow}{\rightsquigarrow\joinrel\mathrel{\mathpalette\@twoheadrightsquigarrow\relax}}
\newcommand*{\@twoheadrightsquigarrow}[2]{%
   \clipbox{{.7\width} 0pt 0pt {-.2\height}}{$\m@th#1\rightsquigarrow$}%
}
\makeatother

\begin{document}

$a \twoheadrightsquigarrow b$\par
$\scriptstyle a \twoheadrightsquigarrow b$\par
$\scriptscriptstyle a \twoheadrightsquigarrow b$

\end{document}

I use the latest texpresso from AUR (ie. current HEAD).

The logs contain some warnings/errors (mostly about fonts), they don't really seem that relevant though. After all, my setup works flawlessly for every other LaTeX code I tried.
