> New changeset f6125114b55f by Serhiy Storchaka in branch '2.7':
> Issue #25108: Backported tests for traceback functions print_stack(),
> https://hg.python.org/cpython/rev/f6125114b55f

The new tests fail on 2.7 branch when Lib/test/test_traceback.pyc is present, because __file__ can contain path to *.pyc files in Python 2.
It is sufficient to run test_traceback twice to reproduce problem:

$ LD_LIBRARY_PATH="$(pwd)" ./python -m test.regrtest -v test_traceback
...
