[Issue 10180] New: mdb.c:2185: Assertion 'rc == 0' failed in mdb_page_dirty()

https://bugs.openldap.org/show_bug.cgi?id=10180

Issue ID: 10180 Summary: mdb.c:2185: Assertion 'rc == 0' failed in mdb_page_dirty() Product: LMDB Version: unspecified Hardware: All OS: All Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: liblmdb Assignee: bugs@openldap.org Reporter: dominik@greysector.net Target Milestone: ---

I'm experiencing a SIGABRT-induced crash in nheko, which uses lmdb for its database (~/.local/share/nheko/nheko/#hash#/{data,lock}.mdb).

The assertion triggering the SIGABRT seems to be happening here: https://git.openldap.org/openldap/openldap/-/blob/master/libraries/liblmdb/m...

The crash happens on every nheko startup since yesterday, so I assume something added to the database is triggering it.
