unexpected EOF on the last and next to last line while creating alias

I am creating alias in .bash_aliases file in Ubuntu 14.04 with reference of this article

I write these

alias agi='sudo apt-get install'
alias upd8='sudo apt-get update'
alias perms='stat -c '%a - %n'
alias dwld='cd ~/Downloads'
alias ..='cd ..'
alias la='ls -alh'
alias hf='history | grep $1'
alias pf='ps -e | grep $1'

I close the terminal and file and start the terminal it always gives error.

bash: /home/ice/.bash_aliases: line 8: unexpected EOF while looking for matching `''
bash: /home/ice/.bash_aliases: line 9: syntax error: unexpected end of file

Please note there is not a line 9, no white space, no special character

What I have done so far

• Removed white space new line and space between lines.

• Remove last two lines but then error comes on last and next to last line ( 6 & 7)

• Deleted the temp file on same folder ending with ~ but error remains.

• Removed the .. and la alias line ( may be it can cause issue) but error still remains.

• I have created an alias with perms from terminal before the creation of .bash_aliases so removed that alias using unalias perms

• check all alias using alias and it show only first 2 alias andd interestingly first two aliases are working fine.

Is this some kind of bugs or what?
