I was not well prepared with my last answer.
First, the combination of
m: Treat string as multiple lines
and
s: Treat string as single line
is still contradictory.
But your problem comes from the string 'C:\\test' containing backslashes.
When you say f.e.
my $str="C:\\test\a\b";
you get 'C:\test' in $str because of the double quotes the backslashes get
interpolated. See perldoc perlop.
So, use single quotes.
Then, in your regex, use \Q and \E to disable pattern metacharacters. See
perldoc perlre.
$orgtext='C:\\test';
$intext =~ s/\Q$orgtext\E/$newtext/gs;
