Package: bash
Version: 4.0-4
Severity: normal
When attemtping to assign to an associative array, bash crashed and
rendered the pty unusable. The following is a cut-and-paste from the
bash session:
$ declare -A foo
$ foo=(dir=$HOME)
malloc: ../bash/hashlib.c:306: assertion botched
free: called with unallocated block argument
last command: foo=(dir=$HOME)
Aborting...
Warning: Program '/bin/bash' crashed.
Expected behavior is for foo["dir"] to equal the expanded value of
$HOME. Perhaps more importantly, expected behavior is that bash handle
the error more gracefully.

Hi, the crash no longer happen in bash version 5.0-6.
However that syntax is wrong. You can either use
$ foo=(dir $HOME)
or
$ foo=([dir]=$HOME)
https://www.gnu.org/software/bash/manual/html_node/Arrays.html
When assigning to an associative array, the words in a compound
assignment may be either assignment statements, for which the
subscript is required, or a list of words that is interpreted as a
sequence of alternating keys and values: name=(key1 value1 key2
value2 … ). These are treated identically to name=( [key1]=value1
[key2]=value2 … ).
If you use foo=(aaa=bbb) you're setting the first element of the foo
array to the literal value "aaa=bbb".
