[Python-Dev] Disabling string interning for null and single-char causes segfaults (original) (raw)

Hi,

2013/3/4 Amaury Forgeot d'Arc <amauryfa at gmail.com>:

The example above is obviously from python2.7; there is a similar example with python3.2:

x = b'\xe9\xe9'.decode('ascii', 'ignore') x == '', x is '' (True, False) ...but this bug has been fixed in 3.3: PyUnicodeResize() always returns the unicodeempty singleton.

Yeah, I tried to reuse singletons (empty string and latin-1 single letters) as much as possible to reduce memory footprint, not to ensure that an empty string is always the '' singleton.

I wouldn't call this a bug.

Victor
