readonly on array broken?

[Bert Münnich]

Hi,

I've just stumpled over the following behaviour:

$ arr=(foo bar)
$ readonly arr
$ arr[0]=bla
mksh: read-only: arr[0]
$ arr=bla
$ echo ${arr[@]}
bla bar

Does the read-only flag not apply to array names in scalar context? I've 
just checked ksh93 and bash. Both of them refuse the third assignment 
from above.


Is this a bug, or am I missing something? I've also checked `typeset -r 
arr[*]' which shows the same behaviour.


I'm running 'MIRBSD KSH R49 2014/01/11'.


Best regards,
Bert

Bert M�nnich dixit:

 $ arr=(foo bar)
 $ readonly arr
 $ arr=bla

 Is this a bug, or am I missing something? I've also checked `typeset
 -r arr[*]' which shows the same behaviour.

Thanks for the report; this seems to be a bug in the code we
inherited from pdksh indeed. Will fix.

bye,
