Android clang version 5.0.300080 (based on LLVM 5.0.300080)
Target: mips64el-none-linux-android
Thread model: posix发现提示print_refer函数有问题
查看print_refer函数
void print_refer(struct med_state print_refer_value)
{
...
}问题出在此函数的入参上，入参传入了一个大的结构体，导致异常
解决办法
修改入参为结构体指针
void print_refer(struct med_state * print_refer_value)
{
...
}
