[求助] 这个是gdb调试错误代表什么意思已有1人参与

Program received signal SIGSEGV, Segmentation fault.
0x00684867 in __strcmp_sse4_2 () from /lib/libc.so.6
上面这句是什么意思

程序如下：
再没有调用add_specie的时候可以运行，但是一旦调用就出现了段错误

【答案】应助回帖

void add_specie (char *new_specie, char *species[],int *n_species)中的参数species是一个指针数组，而new_specie是一个指针。调用add_specie处传入的参数类型不符，而且二者在 if (strcmp (species, new_specie) == 0)不正确的使用，把[]去掉试一试。
