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: [email protected]
Reporter: [email protected]
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/mdb.c?ref_type=heads#L2185
The crash happens on every nheko startup since yesterday, so I assume something
added to the database is triggering it.
Full backtrace from gdb:
...
(gdb) run
Starting program: /usr/bin/nheko

Looks like this was reported to nheko already, but they don't know what's
causing it: https://github.com/Nheko-Reborn/nheko/issues/1303 .
