             Bug #: 11680
           Summary: scan-build errors on c++ includes in .c files, while
                    clang++ does not
           Product: clang
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Static Analyzer
        AssignedTo: kremenek at apple.com
        ReportedBy: fedorabugmail at yahoo.com
                CC: llvmbugs at cs.uiuc.edu
    Classification: Unclassified


clang++ and g++ both successfully build my code which has source files with
extensions cpp and c . However scan-build complains about the presence of C++
includes in any file with a .c extension and does not analyze those files.
Using the --use-c++ switch causes the entire analysis to fail.

The command line used for compilation is:
g++ -O3 -Wall \
<list_of_files>

Adding the option --use-c++ causes the below error:
~/llvm/llvm/tools/clang/tools/scan-build/scan-build --use-c++ g++ \
<list_of_files>

Can't exec "<first_file_in_list.cpp>": Permission denied at
~/llvm/llvm/tools/clang/tools/scan-build/scan-build line 923.


scan-build will fail on this code, but clang++ will succeed.

#include <string>

int main(int argc, char * argv[])
{
  std::string temp;
  return 0;
}
