Description Dave Malcolm 2010-07-14 20:11:16 EDT
Am seeing occasional assertion failures in the garbage collector.

These are typically reference-counting errors _somewhere_ in one of the DSOs linked into the python process, and are thus hard to track down.

See e.g. bug 613917

Arguably we could build without assertions, but this could well turn these errors into segfaults rather than asserts.

I've written a patch that changes these assertions so that they also attempt to print the repr() of the problem object to stderr before aborting, in the hope of better crash reports.
