We can shadow local readonly variables. What we cannot are global
readonly variables.
It seems to me a bug. While the following works,
$ bash-dev -ec 'T(){ local -r v=; }; trap T 0; F() { local -r v=; exit; }; F'
the following fails
$ bash-dev -e <<< 'T(){ local -r v=; }; trap T 0; F() { local -r v=; exit; }; F'
main: line 1: local: v: readonly variable
Tested on the current devel 87a6e89e (+ define(relstatus, release) in
configure.ac)
