RE24 has had some code reworking in the connections area, due to some race conditions that were being triggered. It would be useful if people could test current RE24 to see if they encounter issues. There are still a number of outstanding issues that need to be resolved before 2.4.14 will be released, but I'd appreciate a head start on making sure that at least make test is passing for folks with this new code in place. So far, it does for both Howard and I, but Michael Ströder has reported failures in his OpenSuSE builds that we can't reproduce.
I found two apparently identical core dumps (from HEAD). The second one was from test045 with hdb (all tests went fine with bdb, apparently). The first one I don't know, as it occurred 12 minutes earlier, the test didn't detect it and I didn't save the log info from the runs. The backtrace looks identical:
test045:

I'm currently using CentOS 5.2 kernel: 2.6.18-92.1.10.el5 Oracle DB: 4.7.25
The db library was built quite some time ago; I do not recall how many patches I applied, though I recall applying some. For this reason, I'm going to rebuild it right now.
