R devel - Jul 2003 - R documentation -- buffer overflow? (PR#3400)

Hi,

I have attached a larger Rd file that causes an error when
compiled by
     R CMD Rdconv -t txt xswms2d.Rd
(for example). If the size is reduced the error vanishes,
see the lines 230 and 527 in the file.

I could not find an error within my text and so my guess
is that there is some buffer overflow within the compiler.

If it is me who has caused the error please let me know --
and many apologies.

Cheers,
Martin

Unfortunately, attachments are always "mangled" when going
through R-bugs;  we strongly recommend to put that file on the
Net, and only send an URL to it.

I know how smart you are, but still, just because you didn't
find it, does not really prove ....  ;-)

I don't think so.  When I use cut and paste to recreate your
file,
and do (in a {t}csh; (ba|k)?sh needs another syntax)

     R CMD Rdconv --debug -t txt xswms2d.Rd >& xswms2d.txt

The resulting file becomes
----------------------------------------------------------
-- read file 'xswms2d.Rd';

mark_brackets:............................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................!

******* Syntax error: mismatched or missing brackets in

\name{xswms2d}
\alias{xswms2d}
\title{Modelling of water flux and solute transport}

<..........>

--------------------------------------------------------------

and is even a bit larger than the original.
I can hardly believe that
  ``Syntax error: mismatched or missing brackets in ...''
is caused by a (perl) buffer overflow.

Best regards to Bayreuth, in any case
