[pypy-svn] r35583 - pypy/dist/pypy/module/__builtin__/test

Author: arigo

New Revision: 35583

Modified:
   pypy/dist/pypy/module/__builtin__/test/test_builtin.py
Log:
(pedronis, arigo)

Detect if we're running on top of a Python with broken dict lookup
semantics (eating all exceptions) and skip a test that this fact
makes fragile.  (Works with 'pypy-c -A', or with a patched CPython.)
