Bug 1729

In Bash 4.0 associative arrays were introduced.  There are some environmental variables that are associative arrays.  One of these variables is the BASH_ALIASES associative array.  Documentation can be found here:

http://www.gnu.org/software/bash/manual/bashref.html#Bash-Variables

In short, it's an active array of the system aliases,  with both the alias and the corresponding command kept track of.

For example, to set:

$ BASH_ALIASES[cdt]="cd /tmp"

would be the equivalent of:

$ alias cdt="cd /tmp"

Setting this variable, the alias is instantly available in that bash environment.

Now, when passing these variables with SSH, ssh doesn't interpret these variables as special.  I've tested this on two different distros, Fedora 12 (OpenSSH_5.2p1) and Ubuntu 9.10 (OpenSSH_5.1p1).  Both give different the same bad result.

My environment file:

$ cat environment 
BASH_ALIASES[cdt]="cd /tmp"
TESTME="This is a test"

On F12 & Ub 9.10:
-after an ssh to Ub 9.10 box, the $TESTME variable is set and can be seen when the 'set' or 'env' command is run. The $BASH_ALIASES variable appears in the list as a regular environment variable, ignoring the associative  There is no "cdt" alias either.  It didn't add this to the associative array.

$ env | grep BASH
BASH_ALIASES[cdt]="cd /tmp"
$
