The limitation to access private functions in std package sounds reasonable.

thanks for your advice, but I'm not aiming at this project. I just wonder
whether gollvm is adaptable to large-scale projects and why this case fails
is enough
^ _ ^
The problem cause by reflect.unsafe_New can be seen solved. Welcome to add
something if anyone has a better answer~
---------------------------------------------------
Then I wonder why gollvm work failed with pthread_join which is a C lib
function
I wrote a demo:
```
package main
/*
#cgo CFLAGS: -I./
#cgo LDFLAGS: -L./
#include "ccode.h"
*/
import "C"
import (
"fmt"
)
func main() {
v := C.try_pthread()
fmt.Println(v)
}
```
```
# include <stdio.h>
# include "ccode.h"
# include <pthread.h>
int try_pthread(){
pthread_t id;
int ret, i = 0;
ret = pthread_create(&id,NULL,(void *)thread,NULL);
for(i=0;i<=5;i++)
{
printf("This is main thread %d\n",i);
//sleep(1);
}
pthread_join(id,NULL);
//gets();
return 0;
}
void thread()
{
int i=0;
for(i=0;i<=5;i++)
{
printf("this is thread %d\n",i);
// sleep();
}
}
```
pthread_create() works well in gollvm but pthread_join() failed...
