Bash Version: 4.1 Patch Level: 2 Release Status: release Description: I am getting a segmentation fault from bash when I try to SSH to a remote server (running RHEL 4.4.5-6). After providing my credentials, the SSH client spits back the "Last login: ..." information, and then just hangs. Out of curiosity, I pressed Ctrl-C and was able to get to a bash prompt. However, it's not the "usual" prompt that I see (it usually has my username, the server hostname, etc). login as: xxxxxxx xxxxx@xxxx's password: Last login: Fri Mar 30 14:33:41 2012 from xxx.xx.xx.xxx -bash-4.1$ echo $0 -bash -bash-4.1$ I tried to run /bin/bash from GDB. After a little hang time, I finally got a SIGSEGV error: (gdb) run Starting program: /bin/bash Program received signal SIGSEGV, Segmentation fault. 0x08067ab5 in yyparse () (gdb) The last (significant) changes that I've made to the system was installing GNU screen (using yum install screen). Screen seemed to hang as well when I tried to start it (I'm assuming because it tried running bash, and got the same segfault). I tried running rpm -V to verify the bash package: -bash-4.1$ rpm -V bash -bash-4.1$ All of my .bash* files seem to check out (.bashrc, .bash_profile, .bash_logout) and have nothing abnormal in them from what I can tell. I can provide those if necessary. Repeat-By: Logging into the server via SSH. Trying to run /bin/bash. -- Thanks, Nick
