Bash Version: 2.01
Patch Level: 0
Release Status: release

Description:
        bash yields an internal-error message upon executing a
        malformed program included below.

Repeat-By:

It is reproducable by running the following simple script:

<cuthere>
#! /bin/bash

read line <&3;
read line <&3;

foobarbaz
</cuthere>

        After executing, the interpreter aborts with a
        ``free: Called with already freed block argument''
        message.

        It works also on bash 2.0.3. Both binaries on which I tryed the
        script above was compiled by Debian project (slink and potato).
