I want to do the process of cutting off the code at the end of the string.
The if part in the list below is omitted.(-O1 and -O2)
I want to switch from icc to icx, but I can't do it with this.
・string.c
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <malloc.h>
int main(void)
{
char string[]={"Language ,1\n"};
char *buffer = malloc(1024 * 3);
char *label,*data;
int len;
char delims[2];
strcpy(buffer,string);
// divide into tokens
delims[0]=',';
delims[1]='\0';
if(NULL==(label=strtok(buffer, delims))) return -6;
if(NULL==(data =strtok(NULL, delims))) return -5;
len = strlen(data);
if(data[len - 1] == '\n') data[len - 1] = '\0'; // <= omit
printf("[%s]\n",label);
printf("[%s]\n",data);
return 0;
}
・icx abnomal
>:~/user$ icx -O2 string.c -o string
>:~/user$ ./string (result)
[Language ]
[1 <- line feed remains
]
・icc (and gcc) is correct
>:~/user$ icc -O2 string.c -o string -diag-disable=1044
>:~/user$ ./string (result)
[Language ]
[1]
