There's a core dump in the statistics support – I don't understand it yet, but here's the interesting stack trace, from the develop branch:

The statistics server opened a btree handle in the session in *conn_btree_apply_internal, then wanders down to *curstat_file_init which opens another btree handle in the same session and then releases it. Then, we return back up to here:
Program received signal SIGSEGV, Segmentation fault.

where we again release the btree handle, only it's already been released and we core dump with a NULL session->dhandle reference.
