** Description changed: + [Impact] + * wget will crash while displaying progress bar under narrow terminal + * Upstream already has fixed this issue in commit 7099f489 and 7cb9efa6 + Steps to reproduce: + 1. execute "wget http://old-releases.ubuntu.com/releases/16.04.0/ubuntu-16.04-desktop-amd64.manifest"; under a narrow terminal (such as width less than 40 characters) + Problems: + 1. The wget crash with segmentation fault + Expected behavior: + 1. wget will not crash + + [Test Case] + After upgrading to the new version, the repeating the above steps should give expected behavior. + + [Regression Potential] + Potential of causing regression is relatively small for a two line change for assertion check + + [Other Info] + + + EDIT(other user): The crash actually happens when the terminal window is too small. When I try to download a big file with wget on Ubuntu 16.04 it crashes after a couple seconds. To reproduce the bug try the following: wget http://releases.ubuntu.com/16.04/ubuntu-16.04-desktop-amd64.iso I've asked another guy on IRC on channel #ubuntu-it to try and reproduce this bug and he said it was crashing also on his machine. evan@HPPC:~$ lsb_release -rd Description: Ubuntu 16.04 LTS Release: 16.04 evan@HPPC:~$ apt-cache policy wget wget: - Installato: 1.17.1-1ubuntu1 - Candidato: 1.17.1-1ubuntu1 - Tabella versione: - *** 1.17.1-1ubuntu1 500 - 500 http://archive.ubuntu.com/ubuntu xenial/main amd64 Packages - 100 /var/lib/dpkg/status + Installato: 1.17.1-1ubuntu1 + Candidato: 1.17.1-1ubuntu1 + Tabella versione: + *** 1.17.1-1ubuntu1 500 + 500 http://archive.ubuntu.com/ubuntu xenial/main amd64 Packages + 100 /var/lib/dpkg/status ProblemType: Crash DistroRelease: Ubuntu 16.04 Package: wget 1.17.1-1ubuntu1 ProcVersionSignature: Ubuntu 4.4.0-21.37-generic 4.4.6 Uname: Linux 4.4.0-21-generic x86_64 ApportVersion: 2.20.1-0ubuntu2 Architecture: amd64 CurrentDesktop: Unity Date: Fri Apr 22 01:34:10 2016 ExecutablePath: /usr/bin/wget InstallationDate: Installed on 2016-04-21 (0 days ago) InstallationMedia: Ubuntu 16.04 LTS "Xenial Xerus" - Release amd64 (20160420.1) ProcCmdline: wget http://releases.ubuntu.com/16.04/ubuntu-16.04-desktop-amd64.iso SegvAnalysis: - Segfault happened at: 0x7f4eac3b7328 <__memset_avx2+392>: rep stos %al,%es:(%rdi) - PC (0x7f4eac3b7328) ok - source "%al" ok - destination "%es:(%rdi)" (0x562969134000) not located in a known VMA region (needed writable region)! + Segfault happened at: 0x7f4eac3b7328 <__memset_avx2+392>: rep stos %al,%es:(%rdi) + PC (0x7f4eac3b7328) ok + source "%al" ok + destination "%es:(%rdi)" (0x562969134000) not located in a known VMA region (needed writable region)!
