[issue25429] Can segfault Python with itertools.chain.from_iterable

[Evan Hubinger]

New submission from Evan Hubinger:

The code

import itertools
it = itertools.chain.from_iterable((f() for f in [lambda: it]))
list(it)

definitely segfaults on Python 2.6, 2.7, 3.3, and 3.4, and probably segfaults 
on other versions as well. The code is clearly incorrect in that the lambda 
references the variable being defined, but it seems like it should raise an 
error instead of segfaulting.

[issue22680] Blacklist FunctionTestCase from test discovery

[Evan Hubinger]

Evan Hubinger added the comment:

I wrote a patch to blacklist FunctionTestCase in TestLoader, and a test to make 
sure FunctionTestCase doesn't show up in the TestSuite after loading a module 
that includes it. The test runs successfully. This is my first patch, so 
feedback would be appreciated if I did anything wrong.
