Hello,

I'm currently investigating, why SVN (subversion) does not work properly 
when built for ptxdist. (At first curious segfault, now corrupt data)

I came to this thread:
https://groups.google.com/forum/#!topic/subversion_users/QX91S90YvWk
which is quite the same, that happens to me.

If I'm looking into ptxconfig I find
PTXCONF_GLOBAL_LARGE_FILE=y
In my opinion, this means, that 64 bit file offsets are used.

Now, if I run a program which checks the sizes of the types off_t, size_t 
and ssize_t:

#include <stdio.h>
#include <sys/types.h>
#include <sys/uio.h>

int main(void)
{
    off_t off;
    size_t size;
    ssize_t ssize;
    struct iovec io_vec;

    printf("sizeof(off_t)=%ld\n", sizeof(off));
    printf("sizeof(size_t)=%ld\n", sizeof(size_t));
    printf("sizeof(ssize_t)=%ld\n", sizeof(ssize_t));
    printf("sizeof(struct iovec)=%ld\n", sizeof(struct iovec));

    return 0;
}

the program returns 4 for off_t, size_t and ssize_t and 8 for struct iovec.

But 4 bytes * 8 bit/byte gives 32 bit.

Could someone please explain me, where I am wrong?

I already tried to recompile my project with GLOBAL_LARGE_FILE disabled, but 
without any success for subversion.

Thank you a lot,

Felix
