No, it's a problem in your client. I can btw reproduce it with the ftp
client from Linux NetKit 0.16 on LinuxPPC.

  'ls -al <something here>' in a command-line ftp client means to save the
result of 'ls -al' in '<something here>' . 

  <something here> is expanded by your FTP client. The ftp server only sees
'ls -al'. So you are probably triggering the glibc bug locally.

  If you want to send a pattern and ls options, quote the space :
  
  ls -al\ ~{
  
  Best regards,
