A little more on this, the following yields a segmentation fault:

rule boost.test-smoke-ts-logger ( test-name-prefix : logger ? )
{
     logger ?= HRF ;

     to-return =
       [ run smoke-ts-static : --log_format=$(logger) : : : 
$(test-name-prefix)-0  ]
       [ run smoke-ts-static : --log_format=$(logger) --log_level=all  : 
: : $(test-name-prefix)-1  ]
       [ run smoke-ts-static : --log_sink=smoke-ts-sink.$(logger) 
--log_format=$(logger)  : : : $(test-name-prefix)-2  ]
       [ run smoke-ts-static : --log_sink=smoke-ts-sink.$(logger) 
--log_format=$(logger) --log_level=all : : : $(test-name-prefix)-3  ]
    ;

    ECHO [ $(to-return[0]).name ] ; # works
    ECHO [ $($(test-name-prefix)-0).name ] ; # does not work
    ECHO [ $(to-return[0]).build-dir ] ; # segmentation fault here
    return $(to-return) ;
}

Any hints more than welcome,
