しかし、問題が gsub に留まらないという問題があります。scan 
とか split とか

p '\\\\\\\\\\\\\\\\'.scan('\\\\')
p '\\\\\\\\\\\\\\\\'.split('\\\\')
=> ruby 1.6.8 (2002-12-24) [i586-linux]
   ["\\", "\\", "\\", "\\", "\\", "\\", "\\", "\\"]
   []
=> -:1: warning: string pattern instead of regexp; metacharacters no longer effective
   ruby 1.8.0 (2003-06-09) [i586-linux]
   ["\\\\", "\\\\", "\\\\", "\\\\"]
   -:2: warning: string pattern instead of regexp; metacharacters no longer effective
   []
