I notice that test_re is failing with a recursion depth limit error on Mac OS X, but only when run under regrtest.py. Running plain works: % ./python.exe ../Lib/test/test_re.py Running re_tests test suite Running from regrtest fails: % ./python.exe ../Lib/test/regrtest.py test_re test_re test test_re produced unexpected output: ********************************************************************** *** line 2 of expected output missing: - maximum recursion limit exceeded ********************************************************************** 1 test failed: test_re Cranking the stack limit up as high as 32MB didn't help, though I don't suppose it should have, given the error message. Bumping the recursion limit up as high as 20000 didn't help either. Anybody else seen this? Skip
