[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; } Intel(R) C Compiler for Intel(R) EM64T-based applications, Version 9.1 Build 20070320 Package ID: l_cc_c_9.1.049 Copyright (C) 1985-2007 Intel Corporation. All rights reserved.
