[求助] 這個是gdb調(diào)試錯誤代表什么意思已有1人參與

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

程序如下：
再沒有調(diào)用add_specie的時候可以運行，但是一旦調(diào)用就出現(xiàn)了段錯誤

【答案】應(yīng)助回帖

void add_specie (char *new_specie, char *species[],int *n_species)中的參數(shù)species是一個指針數(shù)組，而new_specie是一個指針。調(diào)用add_specie處傳入的參數(shù)類型不符，而且二者在 if (strcmp (species, new_specie) == 0)不正確的使用，把[]去掉試一試。

贊一下
