In zsh (3 or 4) was where I found that output of a program -- which was being printed just fine in bash -- was not shown in the terminal anymore. Turns out that making shell to print a newline (most likely via shell prompt if not by some option), program output was being displayed on the terminal again. (Program might also have been updated to print a newline at the end.)
