I think it's not sed, but your shell that's causing these problems.
In particular, the behaviour of quoted strings may well not be what
you think it is: the \\ inside "" quotes may not survive unharmed.

In Linux, the problem almost certainly is caused by shell argument
handling. Note the difference in output:

acp3bf:~$ echo "s/test/\\/"
s/test/\/
acp3bf:~$ echo 's/test/\\/'
s/test/\\/
