c - 无法理解为什么我有这些错误：无效读取大小1和Syscall参数unlink（路径名）指向不可寻址的字节

Question

我正在做一个练习，除此之外，我必须从txt文件中读取配置信息，并使用它们来设置服务器。我的代码似乎工作，服务器正常启动，各种缓冲区包含从文件中获取的信息，但启动我的程序与valgrind返回这些错误，我无法理解我错了什么。

这是主要的

#define _POSIX_C_SOURCE 200809L
#include <stdio.h>
#include <unistd.h>
#include <stdlib.h>
#include <assert.h>
#include <string.h>

#include <config.h>

char* UNIXPATH1=NULL;

void cleanup(){
    if(UNIXPATH1!=NULL)
        unlink(UNIXPATH1);
}


int main(int argc, char *argv[]) {

    FILE *fileconf=fopen("./try/in.txt","r");
    if(fileconf==NULL){
        fprintf(stderr, "File error
");
        return -1;
    }
    set_conf(fileconf);
    UNIXPATH1=malloc(strlen(returnUnixpath())*sizeof(char));
    strncpy(UNIXPATH1,returnUnixpath(),strlen(returnUnixpath()));

    cleanup();
    atexit(cleanup);

    FILE *fileout=fopen(UNIXPATH1,"w");
    if(fileout==NULL){
        fprintf(stderr, "File error
");
        return -1;
    }

    fputs("hello",fileout);
    fclose(fileout);
    free(UNIXPATH1);

    return 0;
}

这是config.h

#include <errno.h>
#include <stdlib.h>

#define MEM_ALL(r,c,msg) 
    if(!(r=c)) {perror(msg); fprintf(stderr, "ERROR: Out of memory
"); exit(errno); } 

typedef int make_iso_compilers_happy;


char* UNIXPATH;


char* returnUnixpath(){
    return UNIXPATH;
}

void set_conf(FILE *file){
    char buffer[4096];
    char* token1;
    char* saveptr1;
    char *array[3];
    int i;
    for(i=0;i<3;i++){
        MEM_ALL(array[i],malloc(1*sizeof(char)),"malloc array[i]");
    }
    i=0;
    char* tmp=malloc(sizeof(char));
    while(fgets(buffer,4096,file)!=NULL){ 
        if(buffer[0]!='#' && buffer[0]!='
' && buffer[0]!=' '){
            buffer[strlen(buffer)-1]='';
            token1=strtok_r(buffer," ",&saveptr1);
            printf("s: %ld",strlen(token1));
            tmp=realloc(tmp,(strlen(token1))*sizeof(char));
            strncpy(tmp,token1,(strlen(token1)));

            for(i=0;i<3;i++){
                MEM_ALL(array[i],realloc(array[i],(strlen(token1)+1)*sizeof(char)),"realloc array[i]");
                strncpy(array[i],token1,(strlen(token1)+1));
                array[i][strlen(token1)]='';  
                if(i!=2)
                    token1=strtok_r(NULL," ",&saveptr1);
            }
            if(strncmp("UnixPath",tmp,8)==0){
                MEM_ALL(UNIXPATH,malloc(strlen(array[2])*sizeof(char)),"malloc unixpath");
                strncpy(UNIXPATH,array[2],strlen(array[2]));

            }
        }

    }
    free(tmp);
    for(i=0;i<3;i++){
        free(array[i]);
    }
    fclose(file);
}

这是in.txt文件

UnixPath         = ./try/o.txt

这是valgrind输出
