My new boost regression test for mingw-w64, gcc-4.7, fails at 
process_jam_log...

    "F:\boost\GCC\release\tools_regression\build\bin\gcc-mingw-4.7.0\release\process_jam_log.exe"
    "F:\boost\GCC\release\results" 0<"F:\boost\GCC\release\results\bjam.log"

    terminate called after throwing an instance of
    'boost::filesystem3::filesystem_error'
       what():  boost::filesystem::status: The operation completed
    successfully: "F:\boost\GCC\release\boost\status\libs"

    This application has requested the Runtime to terminate it in an
    unusual way.
    Please contact the application's support team for more information.

Any ideas on the failure or a good work-around?  --pjl-toolkit?
