I'm not sure exactly what we did to produce the original bug report.
You *may* be able to reproduce this bug by:

1. Getting the Boost CVS state (see
   http://www.boost.org/more/download.html#CVS)

2. going to the libs/iterator/test subdirectory

3. Issuing the compile command shown in the bug report.  Make sure
   the Boost root directory is in the #include path.

Note that
http://boost.sourceforge.net/regression-logs/cs-Linux/developer_result_page.html#iterator
still shows one compiler bug for GCC-3.4/CVS on this library (a test
which is supposed to fail to compile does not).  You can find many
others by scanning the gcc-3.4 column at
http://boost.sourceforge.net/regression-logs/cs-Linux/developer_summary_page.html.

HTH,
