Today at Sage Days we tried slices on a few large arrays (no mmap) and found that slicing breaks on arrays somewhere between 2.0e9 and 2.5e9 elements.  The failure mode is the same, no error thrown, basically nothing happens<br>

<br>This was on one of the big sage machines. I don&#39;t know the specific OS / CPU but it was definitely 64 bit and lots of available memory etc.<br><font color="#888888"></font></blockquote><div><br>Can you try slicing with an explicit upper bound? Something like a[:n] = 1, where n is the size of the array.<br>
