Hi, I found this test caused a bus error on current trunk:
<pre>
import numpy as np
from StringIO import StringIO as BytesIO
from numpy.testing import assert_array_equal
def test_2d_buf():
dtt = np.complex64
arr = np.arange(10, dtype=dtt)
# 2D array
arr2 = np.reshape(arr, (2, 5))
# Fortran write followed by (C or F) read caused bus error
data_str = arr2.tostring('F')
data_back = np.ndarray(arr2.shape,
arr2.dtype,
buffer=data_str,
order='F')
assert_array_equal(arr2, data_back)
</pre>
gdb run gives ...
test_me3.test_2d_buf ...
Program received signal SIGBUS, Bus error.
