Forwarding std::string as a parameters to nested reactors does not work as expected

Hi.

This program in the Cpp target did not work as I expected:

target Cpp;

main reactor(s: std::string = "Default", a:int=0) {
  reaction(startup) {=
    reactor::log::Info() << "Main: s=" <<s <<" a=" <<a;
  =}

  r  = new R(s=s, a=a)
}

reactor R(s: std::string = "Default", a:int=0) {
  reaction(startup) {=
    reactor::log::Info() << "R: s=" <<s <<" a=" <<a;
  =}
}

Output:

bin/Test -a 123 -s Hallo
[INFO]  R: s= a=123
[INFO]  Main: s=Hallo a=123

I got the intended behavior by doing the following modification:

r  = new R(s= {= std::string(s)=}, a=a)

That is interesting it definitely looks like a bug. Thanks for reporting.
