Bug#313219: gnome-vfs2 crashes in read_entire_file with HAL and Linux 2.4

[Ivan Wong]

Hi,

Attached please find the source of my testing program. In fact, it
actually does:

int main()
{
        int fd;

        fd = open("a.c", 0);
        posix_fadvise (fd, 0, 0, POSIX_FADV_SEQUENTIAL);
        close(fd);
}

If I compile with `gcc -D_POSIX_C_SOURCE=200112L a.c`, no error.

I tried to build it using the same environment as gmoe-vfs2's modules by:

1. copy a.c to gnome-vfs2-2.10.1/modules
2. adding these two lines to Makefile.am

bin_PROGRAMS = a
a_SOURCES = a.c

3. `make a`
4. `./a` -> Segmentation fault

Now it's obviously that it's something to do with the building
configuration.

It crashes when I re-use the original libfile.so
