[New-bugs-announce] [issue26428] The range for xrange() is too narrow

[Serhiy Storchaka]

New submission from Serhiy Storchaka:

The xrange() object works with integers in the range of C long, not Py_ssize_t. Thus the idiomatic expression xrange(len(seq)) can fail for real sequences if sys.maxint < sys.maxsize (e.g on 64-bit Windows).

Proposed patch changes the xrange() implementation to use Py_ssize_t instead of C long.
