Reference Number : DPD200008448, DPD200137998


Version : All the 10.x, 11.x compilers and the older versions.


Operating System : Linux, Windows


Problem Description : 
    Test case 1: test.c
             int round(float in);
             int foo(float in)
             {
                  int res=round(in);
                  if(res !=0) res = 1;
                   return res;
              }

        Test case 2: test.c
              float memcpy(char*, char*, int);
              float res;
              void foo(char* in, char* out)
              {
                   res = memcpy(in, out, 100);
              }
     Test case 3: test.c
             double pow();
             void bar(double);
             void foo()
             {
                  int a=0;
                  int b[1]={255};
                  bar(pow(b[a],2));
             }
     compile the test case: icl test.c -c
The compiler will report the internal error 0_0, or the internal error 0_1279, or the internal error 0_1208 etc in difference cases.
This is the problem in all the cases where the compiler recognize something (defined by user differently than in compiler intrinsics table) being an intrinsic call and expand this call inline.
Resolution Status : 
1. Change the function name to your own name different to the compiler intrinsic function. For example, change 'round' in case 1 to 'myround', change 'memcpy' in case 2 to 'mymemcpy', change 'pow' in case 3 to 'mypow'.
2. Include the compiler head files to use the intrinsic functions provided by compiler instead of to define your own. Be carefull to the compiler warnings for incompatible declarations during compilation stage.
