True but the way I read that conversation was that DWARF2 EH worked if callbacks weren't used or would work with callbacks so long as -fexceptions was used. Maybe I read that incorrectly though. >/////////////////////////////////////////////////////// > >http://www.cygwin.com/ml/cygwin/2004-11/msg01017.html > >This message seems to be talking about DWARF2 debug >output. Or does -gdwarf-2 have any effect on EH? As you can see, I didn't do *any* weeding of results. ;-) >/////////////////////////////////////////////////////// > >My goal is to build gcc/g++ that use Dwarf2 EH.

You might want to check out the gcc list too. There are apparently issues with sjlj that transcend Cygwin and Windows targets. Perhaps crap-tastically poor performance is one of those things as well. ;-) -- Larry Hall http://www.rfk.com RFK Partners, Inc.
