@Sergey this file is much faster to crash reliably here (see weirdness 1 for instructions). It seems the same error as #58893.
Here at some point I got data llocated by T.17, freed by T.12, and with a read error by T.16,
SUMMARY: AddressSanitizer: heap-use-after-free //source/blender/blenkernel/intern/mesh_runtime.c:184 in BKE_mesh_runtime_clear_edit_data

Hi Sergey,
I have just tried it on
ea33b90a1band Items 1 and 3 are still valid (hard crash).Sorry to reopen tickets, but its the exact same problem.
Probably was re-introduced by
d3e0d7f082. Would need to have a closer look and ensure thatLIB_ID_COPY_RUNTIMEis only used inside of the modifier stack, but not when creating mesh for the first result.Tomorrow is more fixes :)
