Dear list,
This is a copy of a mail sent to Max Kuhn, original author and
maintainer of the odfWeave package, which seems not to have received it.
It reports a problem that seems to be very implementation specific
(reproductible on three Debian testing amd64 machine, does *not* happen
on two i686 Debian testing systems, does *not* happen on an Ubuntu 11.06
amd64 machine) and therefore not attributable to odfWeave itself (which
is pure R) but to a software component it uses (XML and the underlying
libxml2, R itself, etc ...), but I need to know how to track this
problem.
Apologies fror cross-posting to r-help and r-debian-sig, but I think
that the issue is ... complicated and might not be as Debian-specific as
it seems at first view.
Sincerely,
Emmanuel Charpentier
Dear Max,
A few days ago, I started to have problems with odfWeave 0.7.17 on a
couple of amd64 systems : the compiled files contained numerous copies
of the source files, more or less interlaced, "and a few copies of the
target productions.
Then I noticed that using an older 32-bit system resulted in correct
files. An attempt with yet another machine (recent i686 netbook)
confirmed that 32-bit systems gave okay results.
Setup : in all machines, I use Debian testing with updates. My packages
are self-compiled (i. e. installed via install.packages()).
I enclose a very minimalist source and the resulting targets. Logs of
execution on 32- and 64-bit systems are affixed after this message.
Since odfWeave is pure R, I doubt that it could be the source of the
problem. This leaves us with two obvious targets : R itself (the Debian
package is current), or the XML library.
Do you have any idea about how to proceed to find the source of the
problem (and how to fix in) ?
Sincerely,
Emmanuel Charpentier

One could note that the user time is almost double of the 32-bit system system
time, notwhistanding the fact that the 64-bit system is about 10x faster than
the 32-bit system.
