Package: pdksh
Version: 5.2.14-3
Severity: normal

Hi,

The following typescript shows that pdksh reports a syntax error
for a `case' statement inside of the `$( )' form of command
substitution.  I looked at the SUSv2 docs, and according to my
reading, this should be a legal shell construct.

Both ash and ksh93 handle this correctly, while bash and pdksh do
not.  Also note that the same `case' inside of either the old
style (back-quoted) command substitution or inside of a sub-shell
`( )' _is_ handled correctly by pdksh.

Note too that if the case selector has the leading (optional) `(',
then pdksh will handle the otherwise same `case' correctly.

Here are some notes regarding the typescript,

    1. !137 - pdksh gives syntax error, new style $( ).
    2. !138 - ok with (2) case selector, new style $( ).
    3. !139 - ok with  2) case selector, old style ` `.
    4. !140 - ok with  2) case selector, sub-shell ( ).
    5. !141 - ok with (2) case selector, sub-shell ( ).

Here is the typescript itself,

    137 jeff ~ $ do_shells 'aa=$( case 1 in 2) ;; esac )'
    ========================================================================
    >> aa=$( case 1 in 2) ;; esac ) <<
    sh: line 1: syntax error near unexpected token `;'
    sh: line 1: `aa=$( case 1 in 2) ;; esac )'
    -- sh -- exit status 2
    -- ash --
    bash: line 1: syntax error near unexpected token `;'
    bash: line 1: `aa=$( case 1 in 2) ;; esac )'
    -- bash -- exit status 2
    pdksh: <stdin>[1]: syntax error: `;;' unexpected
    -- pdksh -- exit status 1
    -- ksh93 --

    138 jeff ~ $ do_shells 'aa=$( case 1 in (2) ;; esac )'
    ========================================================================
    >> aa=$( case 1 in (2) ;; esac ) <<
    -- sh --
    -- ash --
    -- bash --
    -- pdksh --
    -- ksh93 --

    139 jeff ~ $ do_shells 'aa=` case 1 in 2) ;; esac `'
    ========================================================================
    >> aa=` case 1 in 2) ;; esac ` <<
    -- sh --
    -- ash --
    -- bash --
    -- pdksh --
    -- ksh93 --

    140 jeff ~ $ do_shells '( case 1 in 2) ;; esac )'
    ========================================================================
    >> ( case 1 in 2) ;; esac ) <<
    -- sh --
    -- ash --
    -- bash --
    -- pdksh --
    -- ksh93 --

    141 jeff ~ $ do_shells '( case 1 in (2) ;; esac )'
    ========================================================================
    >> ( case 1 in (2) ;; esac ) <<
    -- sh --
    -- ash --
    -- bash --
    -- pdksh --
    -- ksh93 --

Hi,

this is fixed with the pdksh → mksh migration.

guy. But he's always right! In every fsckin' situation, he's right. Even
with his deeply perverted taste in software and borked ambition towards
broken OSes - in the end, he's damn right about it :(! […] works in mksh
