valgrind mips不显示堆栈跟踪

Question

我在mips平台上使用valgrind 3.13，但是我编写了一个测试程序，发现valgrind没有跟踪到文件行号，对于x86它运行正常。可能是什么问题？

# valgrind --trace-children=yes --leak-check=yes --num-callers=20 /tmp/a.out

下面是我的test.c，使用mips工具链编译，选项为“-g -O0”

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

func1()
{
    int *x=malloc(10*sizeof(int *));
    x[10]=10;
    printf("in func1:x[10]=%d\n", x[10]);
}

main()
{
    char buf[2];
    char buf2[10];

    strcpy(buf,"test buf\n");
    printf("buf=%s\n", buf);
    func1();
}
