--- Comment #19 from John Marino <gnugcc at marino dot st> --- ah sorry, I always seem to conclude wrongly that stack checking requires unwind support. I'm not sure why I always conflate those two things. So this patch was proposed 9 months ago but never got committed? Or was it only partially committed? Will stack-check support get added soon? Thanks, John
