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
Reading mesh file: lid.msh ...
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;
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.
