[SciPy-dev] segfault during scipy.test(1) - Solaris 8, Sun compilers

[Skip Montanaro]

Python is crashing on me during scipy.test(1) (Solaris 8, Sun compilers).
The start of the traceback in dbx looks like:

  [1] copy_ND_array(in = 0x7771d8, out = 0x777a70), line 780 in "fortranobject.c"
  [2] array_from_pyobj(type_num = 9, dims = 0xffbeaa3c, rank = 2, intent = 97, obj = 0x7771d8), line 556 in "fortranobject.c"

  [9] fast_function(func = 0x7d9c50, pp_stack = 0xffbeb4a0, n = 1, na = 1, nk = 0), line 3164 in "ceval.c"

Line 780 of F2PY's fortranobject.c is

  PyArray_VectorUnaryFunc *cast = in->descr->cast[out->descr->type_num];

The value in out->descr->type_num (and in->descr->type_num for that matter)
is -18789104, which is clearly out of range for an element of PyArray_TYPES.
(Why doesn't Numeric define it as such in its PyArray_Descr struct?)

Does this seem familiar to anyone?
