problem. StringValueCStr modifies the argument and it should be
preserved while the string StringValueCStr returns is used.
Since the string is used by caller, the modified argument should be
hold by caller. Actually
GC.stress = true
def (o=Object.new).to_str()
"universal"+"_newline"
end
"\u3042".encode(o, "")'
causes curious warning:
