Bug#626379: libc6: Static binaries fail with __getpagesize: Assertion `_rtld_global_ro._dl_pagesize != 0'

Package: libc6
Version: 2.13-2
Severity: normal

Hi,

static binaries that trigger loading of shared objects (libnss) fail
with the following assertion.

/tmp> cat a.c
#include <pty.h>
#include <stdlib.h>
int main()
{
  int a, b;
  openpty(&a, &b, 0, 0, 0);
  return (int)malloc(123);
}
/tmp> gcc -static a.c  -lutil
/tmp> ./a.out
a.out: ../sysdeps/unix/sysv/linux/getpagesize.c:32: __getpagesize: Assertion `_rtld_global_ro._dl_pagesize != 0' failed.
/tmp>

Other example:
/tmp> cat b.c                
#include <pwd.h>
int main()
{
  getpwnam("root");
  return 0;
}
/tmp> gcc -static b.c
/tmp/ccZB6Ooy.o: In function `main':
b.c:(.text+0x11): warning: Using 'getpwnam' in statically linked applications requires at runtime the shared libraries from the glibc version used for linking
/tmp> ./a.out
a.out: ../sysdeps/unix/sysv/linux/getpagesize.c:32: __getpagesize: Assertion `_rtld_global_ro._dl_pagesize != 0' failed.
/tmp>



Thanks,
  Adam
