Machine Type: x86_64-pc-linux-gnu
Bash Version: 5.1
Patch Level: 4
Release Status: release
Description:
I was typing a command and want to use <Tab> to complete a program name
after the following code:
tig -C "$(dirname "$(base
but bash shows me a "bash: unexpected EOF while looking for matching
`)'" error.
At first I found a similar issue in bash-completion here:
https://github.com/scop/bash-completion/issues/189. But as I commented in that
issue report, I can reproduce this bug even in vanilla bash. So I am now
reporting this bug to bash.
Repeat-By:
0. I tried to use the vanilla bash with steps 1-3, they can be skipped
1. Removed `bash-completion` package
2. Moved away my .inputrc for `readline`
3. Start bash with
$ bash --noprofile --norc
4. Type (The first $ sign is shell prompt):
$ "$(dirname "$(base
5. Press <Tab> key
6. The following message appears:
bash: unexpected EOF while looking for matching `)'
7. Type again:
$ "$(dirname "$(base
8. Press <Tab> key again
9. The following message appears, and shell quits:
free(): double free detected in tcache 2
Aborted (core dumped)
