run error on x86-64 OpenSuse 11.1

[Paean]

Hi, all.

I compiled the serial version OpenFVM1.1 successfully, while I encountered a realloc error after typing

../OpenFVM lid f 1.

The following messages were given. (the nbpointers part is for debug)

d) Pre-conditioners list
0-None
1-Jacobi
2-SOR
3-ILU

Done.

Reading mesh file: lid.msh ...
Done.
nbpointers = 1
nbpointers = 2
nbpointers = 3
nbpointers = 4

I found that the error occurred at the following code segment.

    for (i = 0; i < 8; i++)
{
        node->nodes[i] = malloc (sizeof(oct_node));
        node->nodes[i]->entities = malloc (node->nbentities * sizeof(int));
        node->nodes[i]->nbentities = 0;
       
        opointer = realloc (opointer, (nbpointers + 1) * sizeof (oct_node));

        opointer[nbpointers] = node->nodes[i];
       
        ipointer = realloc (ipointer, (nbpointers + 1) * sizeof (int));  //here when i =3 and nbpointers = 4

        ipointer[nbpointers] = node->nodes[i]->entities;
        nbpointers++;
        OctCreateNode (node->nodes[i], node, i);

    }

I am wondering if there are any one can help me out of this problem.

Thank you very much.

There was a problem before with 64bit system. Could you try and see if it happens in the latest SVN snapshot?

I tried the latest SVN snapshot. It has been working well until now. Thank you very much.
