Python 2.3a1 and the current CVS version abort with the following error message when executing the attached test script: Fatal Python error: D:\Python-current\dist\src\Objects\descrobject.c:10 object at 007C3208 has negative ref count -1 This happens only in the debug build, both on Linux (with configure --enable-unicode=ucs4 --with-pydebug and 2.3a1) and on Windows (with the debug build and current CVS). |

Logged In: YES user_id=33168 I'm not running w/--enable-unicode=ucs4, but I still get the problem. I've simplified the test, but only a little so far. The problem did not affect 2.2.2, only 2.3. |

Logged In: YES user_id=33168 8/6/2002 works without complaints, 8/8/2002 breaks, 8/7/2002 breaks with a different error message: Objects/typeobject.c:466: subtype_dealloc: Assertion `g->gc.gc_refs != (-2)' failed. All dates are American, ie, August, 6-8. The change corresponds to Object/typeobject.c: 8/6 - 2.165 works 8/7 - 2.166 assertion listed above 8/8 - 2.167 assertion in bug report (current) Guido made all the changes, assigning to him. :-) |

Logged In: YES user_id=6380 Fixed in CVS, typeobject.c 2.203. Much thanks to Tim, who understands the trashgcan code much better than I do. Explanation is in the code. I checked that none of the three examples breaks with the new code. |

I'm still seeing a negative ref count error with a fresh debug build after
cvs up...

Logged In: YES user_id=31435 Skip, which program were you running? I don't see any calls to dir() in any of the programs attached to this bug report, so I doubt that this bug report has anything to do with what you're seeing. |

Logged In: YES user_id=44345 I was running a unittest script for the nascent csv module. After posting, I noticed that there was a bug in the test code (at the Python level), but the C code underneath seems fairly solid. (Based on Object Craft's csv module which is pretty stable.) |

Logged In: YES user_id=31435 Please open a new bug report then. The cause of what you're seeing almost certainly has nothing to do with this bug report (for starters, you're nowhere near subtype_dealloc()), so mixing it in here is just going to cause ongoing confusion (as it already has). |
