fdopen/fflush problem

[黄建忠 <jianzhong.huang@i-soft.com.cn>]

Hi, there,
I encounter a problem about fdopen and fflush with musl, here is the code:

#include <stdio.h>
#include <stdlib.h>
#include <fcntl.h>

int main()
{
char filename[17] = "/tmp/abcdeXXXXXX";
int fd = mkostemp(filename, O_WRONLY|O_CLOEXEC);
printf("filename: %s\n", filename);
if(fd < 0)
printf("fd error\n");

FILE *f = fdopen(fd, "we");
fputs("test string\n", f);
fflush(f);

if(ferror(f))
printf("file error\n");

fclose(f);
}

As expected, the final file should contains one line and no ferror reported.

Anybody can help to check it?
