[Intel C++/Linux] bogus/inconsistent warning #279 on !"..."
-----------------------------------------------------------

                 Key: STDCXX-487
                 URL: https://issues.apache.org/jira/browse/STDCXX-487
             Project: C++ Standard Library
          Issue Type: Bug
          Components: External
         Environment: Intel C++ 9 and 10/Linux
            Reporter: Martin Sebor


>From https://premier.intel.com/premier/IssueDetail.aspx?IssueID=431380:

The warning below is not justified and should not be issued. It produces noise for the common
idiom: assert(!"...") used, for example, in case and switch statements to indicate unhandled
cases. (I believe more recent versions of the EDG front end than the one used by icc 9 do
not issue the warning anymore.)

$ cat t.cpp && icc -V t.cpp
int main (int argc, char**)
{
(!1 == argc) ? (void)0 : (void)0;
(!"" == argc) ? (void)0 : (void)0;
