New submission from Ned Deily:
Seen on the AMD64 Mountain Lion Optimized [SB] 2.7 buildbot
(http://buildbot.python.org/all/builders/AMD64%20Mountain%20Lion%20Optimized%20%5BSB%5D%202.7):
test test_doctest crashed -- <type 'exceptions.AssertionError'>: filter
('backquote not supported', SyntaxWarning) did not catch any warning

AssertionError: filter ('backquote not supported', SyntaxWarning) did not catch
any warning
The same failure is seen in test_syntax and test_zipimport_support.
That buildbot builds the interpreter --with-pydebug but runs the test suite
with -OO:
./python.exe -Wd -3 -E -tt -OO -R ./Lib/test/regrtest.py -uall -rwW
I am able to reproduce the buildbot failures when run as above. Without "-OO",
the tests no longer fail.
