Sorry for the typo, that's what you get for extracting test case. This one is
better.

With this one I can reproduce my original worry indeed:

[~]> g++ -c --std=c++0x testcase.cpp -Wall -Werror
testcase.cpp:2:17: error: unterminated raw string
testcase.cpp:2:15: error: expected primary-expression at end of input
testcase.cpp:2:15: error: expected ‘,’ or ‘;’ at end of input

Since the trigraph eats up the trigraph terminator, it's not terminated. Now
imagine a second constant in the same file and you do get a corrupted output.
