      Description

      The attached (3 line) testcase ( MDEV-26381_1.sql ) is not finalized. Whilst I am confident that the said testcase can produce the assertion as-is (it was reduced to this based on seeing the assert or not), reproducing the crash itself is not straightforward. It may be highly sporadic, or more likely dependent on some system condition (like running out of file descriptors, some OS shortcoming, or similar). As discussed elsewhere, the issue is likely not confined to partitioning but is rather related to the accessing of many .ibd files whilst running into a [bad] file descriptor issue,. There is a core file and Marko will analyze that one. [DONE]

      Possibly related: MDEV-20648 , MDEV-26293 (likely)
