Issue #766 has been updated by Ittay Dror. as mentioned, this happened in other machines. i'll try creating a fresh environment and check it there. however, i won't be in the office next week, so don't hold your breath ;-) in the meanwhile, what i saw is that the function that failed was 'puts' (actually 'write'), and it failed trying to output a very long string. is there some kind of windows limitation on the length of the output? ---------------------------------------- http://redmine.ruby-lang.org/issues/show/766 ---------------------------------------- http://redmine.ruby-lang.org
