Bash Version: 5.0
Patch Level: 3
Release Status: release
Description:
There seems to be unexpect (a bug?) behaviour with bash's handling of
array assignments.
Specifically, if you try to assign an array element a value containing
that same array value, it fails to work.
See example below :)
Bug confirmed by the folks in #bash on Freenode - unable to explain
what is happening.
Repeat-By:
declare -A foo
foo=(["key"]="value1")
declare -p foo
foo=(["key"]="${foo["key"]} value2")
declare -p foo
The above should result in 'foo["key"]' having a value of 'value1
value2', but the result is simply ' value2', which I believe to be incorrect
behaviour.
