Christophe,
Didn't you forget to add -save-temps in the testcase?
I'm seeing it failing because:
g++.dg/cpp/string-3.C -std=c++11 : output file does not exist
UNRESOLVED: g++.dg/cpp/string-3.C -std=c++11 scan-file BEGIN
"R\\"(\\n)\\""\n END
Surprisingly we emit a .i file, but I'd also flubbed the regexp with
insufficient escaping.
Fixed thusly.
