--- Comment #4 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
Sorry I didn't use the right compiler. If I do so, I get
* thread #1, queue = 'com.apple.main-thread', stop reason = EXC_BAD_ACCESS
(code=EXC_I386_GPFLT)
frame #0: 0x0000000101443613 f951`splay_tree_min(sp=0x0000000100000001) at
splay-tree.c:501:11
498 if (!n)
499 return NULL;
500
-> 501 while (n->left)
502 n = n->left;
503
504 return n;
Target 0: (f951) stopped.
