Bug #1441: String#gsub handles backslashes incorrectly
http://redmine.ruby-lang.org/issues/show/1441

Author: shawn .
Status: Open, Priority: Normal
ruby -v: ruby 1.8.7 (2008-08-11 patchlevel 72) [x86_64-linux]

Was creating regexps in ruby and noticed this problem:
"\\\\"
=> "\\\\"
(printf => \\)
"b".gsub("b","\\\\")
=> "\\"
(printf => \)

it takes 6 or 8 backslashes to get 2, its running something twice:
"b".gsub("b","\\\\\\")
=> "\\\\"
(printf => \\)

everything is the same using single quotes

also occurs in ruby1.9 (-v ruby 1.9.0 (2008-06-20 revision 17482) [x86_64-linux])
