llvm dev - Nov 2002 - [LLVMdev] problem with llvmgcc and lli

Finally lli and llvmgcc can work under my directory. I wrote the following
simple program and compiled it using gcc and then run it without any
problem.  But when I tried to compile it using llvmgcc and lli, llvmgcc
gave me the following error message which I cannot understand:

xli3|csil-suna37|~/cs426|[181]% llvmgcc test.c -o test
test.c: In function `init':
test.c:10: warning: cast to pointer from integer of different size

When I run it using lli, it even gave me the following segmentation fault:
EXCEPTION OCCURRED [Segmentation Fault]:
>#0. int "main"()
        store uint 1, uint* %cast216
Breakpoint hit!
#5      store uint 1, uint* %cast216
#5      store uint 1, uint* %cast216
lli>

Could you please let me know what's wrong with this program? The program
is attached as follows:

Thanks,

#include <stdio.h>

struct a {
        int b;
        int c;
};

struct a  *init( )
{
        struct a *tmp = (struct a *)malloc(sizeof(struct a));

                                return tmp;
}


int main()
{
        struct a *h;

        h = init();

        h->b = 1;
        h->c = 2 + h->b;

        printf("%d, %d\n", h->b, h->c);

        free(h);
}
