subversion crash

Normally I run subversion under apache as I like being able to get at my stuff from anywhere. But recently, some upgrade has broken. I’ve now started seeing broken checkouts. This is most disconcerting. For now, I’ve switched to accessing it over the filesystem which seems to work ok. But an update on that mailing list post…

I’ve managed to get a stack trace. I switched to gdb 5.3 instead of the system default (6). And that managed to get me this stack trace:

Now I need to start building debug versions of apache and subversion in order to start making some sense of that. It’s my suspicion that subversion is sending bad buckets to apache somehow.
