Description Hedayat Vatankhah CLA 2011-11-01 07:52:33 EDT 
Build Identifier: I20110613-1736

Unfortunately, I have many issues with CDT 8.0 indexer. It works much worse than CDT 7.0 on my projects. I don't know why, but anyway I have tried to get some error messages. One of the problems which is probably new (since it causes some mistakes which didn't exist in CDT 7.0) is the following example. In this example, It says: unbounded string encountered after #ifdef line:

#define PR ""

void test()
{
#ifdef _DEBUG
        PR"";
#endif
}


int main(int argc, char **argv)
{
    return 0;
}


Reproducible: Always

Steps to Reproduce:
Put the above code in a source file.

One more comment: PR"" was the minimal construct that caused this problem. PR prefix is not the only prefix with this problem. The actual word which caused this problem was PRIuPTR"" so it is not limited to PR.

Yep, any identifier that ends with R will trigger the issue.
