New issue 735: Assertion rewriting triggers internal assert in compile.c on
debug builds
https://bitbucket.org/pytest-dev/pytest/issue/735/assertion-rewriting-triggers-internal
David MacIver:
When running pytest-2.7.0 on a debug build of Python 3.4.3 against the
following code, I get an internal assert triggered in Python:
```
#!python
def test_trivial():
assert True
```
The following is the error:
```
$ ~/snakepit/python3.4-debug -m pytest test_rewriting.py --capture=no
============================================= test session starts
=============================================
platform linux -- Python 3.4.3 -- py-1.4.26 -- pytest-2.7.0

Assertion `PyUnicode_CompareWithASCIIString(name, "None") &&
PyUnicode_CompareWithASCIIString(name, "True") &&
PyUnicode_CompareWithASCIIString(name, "False")' failed.
Aborted
```
If I switch pytest to --assert=plain the error goes away.
It seems likely there's some sort of Python bug underlying this, but I figured
you'd want to know about the problem anyway and I don't have a minimization
smaller than "all of pytest" so don't feel able to report this to cpython
myself.
