Amaury Forgeot d'Arc added the comment: After some hard debugging: - doctest.debug_src() is unlucky enough to trigger a garbage collection just when compiling the given code. - gc collects unreachable objects, among them is an instance of the class doctest._SpoofOut, which derives from io.StringIO. - The debugger steps into io.IOBase.__del__
Some possible directions: - Change the gc thresholds. A very temporary workaround to make the test pass. - Find the cycle involving the SpoofOut object, and try to break it in doctest.py. - Find a way to disable pdb tracing when the gc is running finalizers. (this is what happens in 2.5: pdb does not step into a C function) - Forget everything, and wait for the io.py object to be rewritten in C. ---------- nosy: +amaury.forgeotdarc __________________________________ Tracker <[EMAIL PROTECTED]> <http://bugs.python.org/issue1540> __________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
