 This is a bug in your shell startup scripts.  GDB isn't starting a new
 login shell; it's starting a new command shell.  You should get the same
 results you would if you ran a shell script using this shell.
 What is your setting of $SHELL?  Bash won't normally do this, although
 zsh will read .zshenv.
