Bash Version: 4.2
Patch Level: 47
Release Status: release



Description:
	When run as rbash, it parses then environment for functions when the 
man page specifically says it does NOT do this.
        It is also UNEXPECTED for bash run as "sh" to import fuctions 
from the environment (which it also seems to do).

Repeat-By:
while running bash:
        export Y=\(\)\ \{\ ignored\;\ \}\;\ /usr/bin/id
        rbash
        (same with sh)
	Note the error message which means rbash and sh are parsing the 
environment to find functions.



Fix:
	When bash is run as rbash or sh it should NOT parse the inherited 
environment for functions (nor for options).

Actually, I suggest bash be modified to ONLY parse the environment for 
functions when it is specifically invoked as bash - and act as rbash 
when invoked as any unrecognized name.
