I take comment #20 back, I was introducing a space after "ls". The test case also works for me.
** Description changed: [Impact] * This bug makes tcsh unusable in Ubuntu 16.10 * Backporting to the stable release is justified as there are still 8 months before end of life [Test Case] - * Open a shell using tcsh, write "rmdi", hit Tab. What should happen? - The command should autocomplete to "rmdir". What happens? tcsh crashes. + * /bin/tcsh -c "ls-F" + This will cause a segmentation fault [Regression Potential] * It is not expected that fixing this bug will cause any regression After upgrading to 16.10, hitting "tab" crashes tcsh.
