This should be fixed as of r54259.

Dear all,
There seems to be a problem with named chunks in Sweave with the version
of R under development (downloaded yesterday). When I sweave the file
toto.Rnw described at the end of this mail (Ubuntu 10.04 LTS), the
function Sweave returns an Internal error:
> utils::Sweave("toto.Rnw")
Writing to file toto.tex
Processing code chunks ...
1 : echo term verbatim (label=a)
2 : echo term verbatim (label=c)
3 : echo term verbatim (label=b)
4 : echo term verbatim (label=d)
Error: chunk 4 (label=d)
Error in eval(expr, envir, enclos) : Internal Sweave error
I did not find the cause of this problem, except that it occurs when
Sweave is called on a file with named chunks. Note that the function
Sweave works fine with the latest stable version of R (both R-2.12.1 and
R-patched). And I found nothing about this problem in the NEWS file of
the development version. I am not sure, but I wonder whether this might
be a bug... could you confirm?
