             Bug #: 53165
           Summary: multiline raw strings as macro arguments
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: joerg.richter@pdv-fs.de


With GCC 4.7.0:

$ cat t.cc
#define XXX( x ) x
char const* str = XXX( R"(
)" );

$ g++ -std=c++0x -o t t.cc
t.cc:2:24: error: unterminated raw string
t.cc:2:1: error: stray 'R' in program
t.cc:3:2: warning: missing terminating " character [enabled by default]
t.cc:2:1: error: missing terminating " character
t.cc:2:17: error: expected primary-expression at end of input
t.cc:2:17: error: expected ',' or ';' at end of input

Following raw string works:
  char const* str = XXX( R"()" );
