So what happens and why, looking at env we find the problem:

It's TERMCAP!
No idea guys, really.
But since this seems to be "legal" it should not blow stuff up. The messages from Rudder, being red, look horrible.

Oh and this was indented, it's just redmine that didn't like what I pasted.

This would work on Linux, where env supports the -0 option:
env -0 | sed 's/"/\\"/g; s/\x0/"\n/g;' | sed 's/^\([^= \t]\+\)=/node.env[\1]="/g;'
(tested on Fedora 21)

- Target version set to 3.1.5
- Pull Request set to https://github.com/Normation/rudder-techniques/pull/771
- How to reproduce updated (diff)
- Found in version(s) old 3.1.2 added
Please check PR @ https://github.com/Normation/rudder-techniques/pull/771.
Changed the way it parses the environment:
Instead of writing a bash script, that is being executed as a module (which apparently also does not handle multi-lined strings), the output of env -0 (null-terminated) is used, and by grepping/sed/tr-ing, we extract the variable names to an array, then populate the node.env by the getenv() built-in function, which was introduced in 3.0.4, and are happy.
I have not found a way to reproduct something similar on Solaris, I was looking into the bash's "set", which outputs all variables in ANSI-C-Like quoting, but not only the environment variables, so this might need additional processing, probably by something like printenv...
