Subject: [Rd] Using \u2030 in plot axis label -> stack smashing
Message-ID: <1158586738.28530.52.camel@gsimpson.geog.ucl.ac.uk>

Dear List

I just noticed the following behaviour in R 2.3.1 Patched (2006-06-13
r38342) and confirmed similar behaviour in R 2.4.0 alpha (2006-09-18
r39383) & R 2.5.0 (2006-09-18 r39383) - which may actually be the same
thing?, that trying to plot the unicode character \u2030 (which should
be in a ? [per mille] sign) in an axis label leads to the following
error:

*** stack smashing detected ***: /home/gavin/R/R-devel/build/bin/exec/R
terminated
Aborted

The simplest, reproducible example I have tried is:

plot(1:10, ylab = "\u2030")

This is on a Fedora Core 5 box. Relevant version/session info below.

I presume this is how you are supposed to enter Unicode characters for
use in stings etc? If so, can anyone else reproduce this - or is this
something peculiar to my set-up and/or lack of fonts?

Cheers

Gav
