    Fix array bounds violation when pty allocation fails. · 6496aec9
    Paul Eggert authored
    * configure.ac (PTY_TTY_NAME_SPRINTF): Use PTY_NAME_SIZE,
    not sizeof pty_name, since pty_name is now a pointer to the array.
    * src/process.c (PTY_NAME_SIZE): New constant.
    (pty_name): Remove static variable; it's now auto.
    (allocate_pty): Define even if !HAVE_PTYS; that's simpler.
    Take pty_name as an arg rather than using a static variable.
    All callers changed.
    (create_process): Recover pty_flag from process, not from volatile local.
    (create_pty): Stay inside array even when pty allocation fails.
    (Fmake_serial_process): Omit unnecessary initializaiton of pty_flag.
