While fixing lint in the `env_init()` function I noticed the magic `A__z` env var. This is a poorly documented mechanism for passing the properties of exported vars to subshells. I...

The *nameref.sh* unit test triggers one of the three remaining bugs found by ASAN. This is the minimum reproducer: ``` typeset +n c x compound c=( typeset -a x )...
If `pathprog()` fails to get full path to a binary through `path_prog()` function, it falls back to searching for the command through a [regular path search](https://github.com/att/ast/blob/5ea5c6878efe1fe4b85d06378aa2b0126452ab9e/src/lib/libast/path/pathprog.c#L131-L137). This seems incorrect and...
**Description of problem:** `pathexists()` function caches file permissions in a [tree structure](https://github.com/att/ast/blob/fda0814cd918bf1d892a27c38be3649406f200d3/src/lib/libast/path/pathexists.c#L42-L47), but does not invalidate the entries. This will return invalid results if file permissions on cached path changes....
