try
{
int error = *(int *)arg;

printf("thread error:\n");
}
catch(int error)
{
printf("catch error:%d\n",error);
}
printf("catch finish\n");
}
int main()
{
pthread_t thread1;
int a =1;
if(pthread_create(&thread1,NULL,func,&a) != 0)
{
printf("create thread failed\n");
return -1;
}
sleep(10);
return 0;

4. This bug also in
gcc-6.2.1 + glibc-2.3
gcc-6.3.1 + glibc-2.3
gcc-6.4.1 + glibc-2.3
5. We found it has been solved in gcc-7.1.1 + glibc-2.5
6. Request:
I'm not sure this bug is caused by gcc or glibc,
Please give me some advice, thanks.
