Bash Version: 2.05

Release Status: release

Description:
        When there is an eval-construct in a function which is 
        called for programmable completion  (complete -F ...)
        bash gets into some unexpected state on the first
        completion attempt which uses this function.
        

Repeat-By:
        1. Define the following function: 
        
            test_func () { eval COMPREPLY=( A B ) ; }
            
        2. use it as completion function:
        
            complete -F test_func xx
            
        3. make an attempt to complete the following:
          
            xx <space> <tab> <tab>
            
          -> A B appears correctly as completion choices.
          
            <enter>
            
          -> New lnput line appears - Nothing else happenes!
             xx is not executed!!
             
             bash remains in this state until a CTRL-C or
             CTRL-D (response: bash-2.05: syntax error: unexpected end of file)
             is enterd.
             
       Remarks: 
       - bash2.04 behaves correctly for that example
       - the example isn't usefull, but demostrates what happenes.
       - the malfunction doesn't depend on which variable 
         is set in the eval-construct (it doesn't work with 
         variables different from COMPREPLY, too).
       - I need the eval-construct to embed filenames containing 
         spaces in the COMPREPLY array:
           eval COMPREPLY=( $(compgen  -P'"' -S'"' -f -X "$excl_pat" 
${COMP_WORDS[COMP_CWORD] ) )
          
          

Fix:
        No idea ;-(
