[Numpy-discussion] Bug? Numpy crash with bad __array_interface__
Thu Aug 7 14:47:28 CDT 2008
As per my previous email, I encountered a strange sometimes-segfault
when using 'numpy.array(thing)' to convert 'thing' (which provides an
__array_interface__) to a numpy array.
The offending __array_interface__ has a 'data' item that is a python
string (not, as specified in the protocol, a pointer to a memory area)
which is too small for the provided array size. Which, in some cases,
causes a segfault.
Is this a bug? That is, should numpy check the size of the
'data' (when 'data' is in fact a sized python object and not just a
bare pointer) against the size of the array and provided typestr? Or
is this too much of a corner case to deal with...
