The problem is around line 1734 of callproc.c in tip:
} else if (PyType_Check(cls)) {
typ = (PyTypeObject *)cls;
buf = alloca(strlen(typ->tp_name) + 3 + 1);
sprintf(buf, "LP_%s", typ->tp_name); <-- segfault is here
Replacing the alloca with a malloc fixes it, so I presume it's hitting the
stack size limit as 2^25 is 32MB (my stack limit is 8MB).
