*Some* of the new ones are "bogus", in a sense that while the XML
produced by process_jam_log is incomplete, we can assert with a
reasonable degree of certainty that the test actually does pass (as
it's the case with the test case you quoted).

We cannot say that for test cases like this, for instance

    Test output: BoostConsulting - algorithm/string - replace / msvc-8.0
    Report Time: Mon, 15 Jan 2007 11:23:51 +0000

    [Reporting Tools Internal Error] This test case's XML is
    missing one or more log entries of the regression run's steps
    associated with the test case's type ("run"). Please contact
    reporting tools maintainers about this problem.

    Compiler output [2007-01-14 17:08:58 UTC]:

        call "C:\Program Files (x86)\Microsoft Visual Studio 8\VC\vcvarsall.bat" amd64 >nul
    cl /Zm800 -nologo @"Z:\results\boost\bin.v2\libs\algorithm\string\test\replace.test\msvc-8.0\rls\adrs-mdl-64\instr-set-optrn\thrd-mlt\replace_test.obj.rsp"


In fact, it's very likely that, despite the absence of any errors in
the output, this one actually fails. The reason why it is likely to be
the case is articulated in the note: the test case is declared as a
"run" test, yet the XML does not contain any output for steps that
follow the test compilation.

If you browse through the newly reported "Internal Error" regressions
in a few different libraries, you will see that most of the actually
into "most likely broken" category.

The XML is missing the output from the "compile" step.

True. I'll see if we can sort these out easily before process_jam_log
is fixed to produce correct XML.
