MrBayes

Hi everyone,

I am trying to have MrBayes (3.2, the CVS version) running on a PPC cluster that runs (64-bit) linux. I tried with both 32 and 64-bit openmpi compilers (gcc). It segfaults at:

tree.c, line 3478, where it says:

/* set all pointers to NULL */
3478 for (i=0; i<t->nNodes; i++)
3479 {
3480 p = &t->nodes[i];
3481 p->anc = p->right = p->left = NULL;
3482 p->index = -1;
...

I tried to debug, but I cannot even read what's in t->nNodes! Any ideas?

Thanks in advance,
-Memo

PS: Here's the entire error message:
