getpagesize() problems

Hi all,
I'm developing a project that uses dietlibc since 0.30 version.
dietlibc works well.
Some days ago I upgrade to dietlibc 0.32 and the project stops to work
for segfault issues.
I investigated and discovered that getpagesize() makes the segfault.
In fact, if I define the PAGE_SIZE directly the project works well.

Then I made some tests with other stupid programs like:
#include <unistd.h>
#include <stdio.h>
#include <sys/user.h>

int main(void) {
	int size = getpagesize();
	int size2 = PAGE_SIZE-1;

	printf("size: %u\n", size);
	printf("size2: %u\n", size2);
	return 0;
}

and compile it like: cc -o test test.c -nostdlib ../dietlibc.a -lgcc
and I got segfault immediately.

Other stupid test:
#include <stdio.h>

int main(void) {
    long long i;

    printf("pid:%d\n", getpid());

    for (i=0; i<10000000000; i++) ;

    sleep(1);
    return 0;
}

same compile instructions and this time the test runs well.
I don't know, maybe I'm wrong, but it seems a getpagesize() issue.
What do you think about that?
Regards,

Michele
