Every so often (roughly once in a thousand runs or so it seems), a server will crash in test050 on master. This test replicates cn=config which is not officially supported yet.

Some output from a gdb session from the core is uploaded here: ftp://ftp.openldap.org/incoming/test050-crash-master-20190628.txt

It's not clear to me how attrs_dup has reached the attribute at 0x170b6a8 unless there was another thread messing with the same structure. str2entry2 is running in another thread, but I wouldn't think it runs on the same entry? Stuff is optimised out in this one.
