Describe the Bug

bhook拦截了dlsym函数
FILE* new_fopen(const char* __path, const char* __mode){
BYTEHOOK_STACK_SCOPE();
return BYTEHOOK_CALL_PREV(new_fopen, __path, __mode);;
}
void* new_dlsym(void* __handle, const char* __symbol){
BYTEHOOK_STACK_SCOPE();
void rs = NULL;
if(strcmp(__symbol, "fopen") == 0) rs = (void)new_fopen;
else rs = BYTEHOOK_CALL_PREV(new_dlsym, __handle, __symbol);
LOGD("dlsym: %s, func:%p", __symbol, rs);
return rs;
}

如果目标应用通过dlsym来调用fopen的时候会崩溃，我看源码中写有
if (0 == stack->frames_cnt) abort(); // called in a non-hook status?
有啥办法解决吗？

把你自己的fopen逻辑写在一个单独函数中？比如new_fopen_impl（里面不包含bytehook的任何宏和调用），然后new_fopen调用new_fopen_impl，new_dlsym也返回new_fopen_impl的地址？

好的，明白了，谢谢
