The PDF at
<a href="https://bugs.debian.org/cgi-bin/bugreport.cgi?filename=D.pdf;bug=728358;att=1;msg=5">https://bugs.debian.org/cgi-bin/bugreport.cgi?filename=D.pdf;bug=728358;att=1;msg=5</a>
does not always render correctly in evince or pdftocairo. The drawing in the
middle of the page disappears at some zoom levels. The PDF contains drawing
commands with large numbers like:
0 0 m
0 2147483647 l
1098 2147483647 l
1098 0 l
W* n
Which means clip to a very large box. I can reproduce this behavior in cairo
with the attached C program. Clipping to a large rectangle will sometimes
cause any further drawing to not happen, though depending on the scaling (set
by calling cairo_scale) it will sometimes work.</pre>
