Package: bash Version: 5.0-1 Severity: normal Dear Maintainer,
While doing my regular upgrade of Sid, I happily discovered that brand new bash version 5.0-1 in the set of installed packages, so I gave it a try. :^) I ran the command `ls` which stuck without showing the output of my home directory while it usually did, and while /bin/ls did show it without much issues. Remembering a similar situation in a long forgotten past in Csh, I ran `unalias ls` and the situation went back to normal. Alas, in my foolishness, I dug deeper in my login scripts to understand why this was affecting me, thinking I introduced a loop of some sort. Instead I discovered that: if an alias ends with a tabulation character, then the hang reappears. Example: $ alias reproducer='true ' $ reproducer _ ...and you should see your shell running at 100% in a monitor like `top`. I'm not sure if I broke something with my nonstandard system, but in case some other maniac of well aligned quote has the same issue, at least this entry exists. As an additional symptom, or lack of, an `strace bash` output of the shell does not show system calls while the interpreter is looping so, either there is no system call during the loop, or I don't strace the right process.
