Yes, expansion needs to be delayed to get the current dimension when 
the list is placed. My error—thank you for the correction. But the 
regression is not resolved. The .tuc file now contains:


["second"]="\\hbox {\\simplealignedbox {12.6pt}{left}{2\\quad
}{\\hbox {\\setbox \\scratchbox \\hbox {Yet another list testing
text xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx
xxx xxx xxx}\\scratchdimen \\STWidth \\relax \\box \\scratchbox }}}",

Still no mention of dobounded text is carried into the list.
Is \limitatetext a option for you because unlike \doboundtext the 
command is unexpandable?


\starttext

\doboundtext {Thus, I came to the conclusion that the designer of a new 
system ...}{.5\textwidth}{...}


\limitatetext{Thus, I came to the conclusion that the designer of a new 
system ...}{.5\textwidth}{...}

Is it an option of which I am aware, yes. Do I desire to use it, no. 
Will I use it? Perhaps, if \doboundtext cannot be repaired. The 
resulting page with \limitatetext has large rivers of white on the page.


But more likely I will look for a hack to use \doboundtext to trim the 
text before writing it to the list, even though it loses the flexibility 
of computing the width dynamically.


Can you point to what changed between the 20150325 version and TL15 to 
break this?

Adding \noexpand before \doboundtext should work.
