[Dotgnu-libjit] Convert a jit_type_ubyte to int = Segmentation fault

[manolo ohara]

Hello.
I'm trying to convert a jit_type_ubyte to int, but it gives me "segmentation fault".
My machine: Debian 6.0 32 bits with the last libjit version.

What's the problem?

#include <stdio.h>
#include <jit/jit.h>

int main(void)
{    jit_int p_memory;
    char memory[65536];
    jit_context_t context;
    jit_type_t signature;
    jit_function_t function;
    jit_value_t tmp1,tmp2,tmp3,tmp4,tmp_index,ubyte_tmp1;
    jit_int index,constant_100000,p_result,result;
        
    index=3;
    memory[index]=0x56;
    
    /* result=memory[index]+10000*/
    
    /* Create a context to hold the JIT's primary state */
    context = jit_context_create();

    /* Lock the context while we build and compile the function */
    jit_context_build_start(context);

    /* Build the function signature */
    signature = jit_type_create_signature(jit_abi_cdecl, jit_type_void, 0, 0, 1);

    /* Create the function object */
    function = jit_function_create(context, signature);
    tmp1 = jit_value_create(function, jit_type_int);
    tmp2 = jit_value_create(function, jit_type_int);
    tmp3 = jit_value_create(function, jit_type_int);
    tmp4 = jit_value_create(function, jit_type_int);
    tmp_index = jit_value_create(function, jit_type_int);
    ubyte_tmp1=jit_value_create(function, jit_type_ubyte);    
    p_memory=jit_value_create_nint_constant(function,jit_type_void_ptr,memory);/* p_memory=&memory*/
    p_result=jit_value_create_nint_constant(function,jit_type_void_ptr, &result); /* p_result=&result*/
    constant_100000=jit_value_create_nint_constant(function,jit_type_sys_int,(jit_int)(100000)); /*constant_100000=100000*/
    tmp_index=jit_value_create_nint_constant(function,jit_type_sys_int,(jit_int)(index)); /*tmp_index=index*/
      jit_insn_store(function, tmp1,p_memory);/* tmp1=p_memory*/
      jit_insn_store(function, tmp2,tmp_index);    /* tmp2=index*/        
      ubyte_tmp1=jit_insn_load_relative(function,tmp1,tmp2,jit_type_ubyte);/*ubyte_tmp1=memory(tmp1+tmp2) */
    tmp3=jit_insn_convert(function, ubyte_tmp1,jit_type_int,0);/*tmp3=(int)ubyte_tmp1*/  /*SEGMENT VIOLATION*/
    tmp4=jit_insn_add(function, tmp3,constant_100000); /*tmp4=tmp3+constant_100000*/
    jit_insn_store_relative(function,p_result,(jit_int)0,tmp4);/* memory(p_result+0)=tmp4*/
    
    /* Compile the function */
    jit_function_compile(function);
    jit_dump_function(stdout,function,"myfunct");
    /* Unlock the context */
    jit_context_build_end(context);

    /* Execute the function and print the result */

    jit_function_apply(function,0,0);


    /* Clean up */
    jit_context_destroy(context);

    /* Finished */
    printf("\nresult=%d\n",result);
    /* Finished */
    return 0;
