> Ok, I understand: it's probably because of [microsoft/mimalloc@469ade8](https://github.com/microsoft/mimalloc/commit/469ade882dbff3226be92e71e2d75d04d84029b1) and has been discussed upstream in [microsoft/mimalloc#1095](https://github.com/microsoft/mimalloc/issues/1095) It's bad that mimalloc forces arm arch to be armv8.1-a. Compiler generates LSE instruction [laddal](https://developer.arm.com/documentation/ddi0602/2025-06/Base-Instructions/LDADD--LDADDA--LDADDAL--LDADDL--Atomic-add-on-word-or-doubleword-in-memory-) for atomic_fetch_add operation. [LSE](https://learn.arm.com/learning-paths/servers-and-cloud-computing/lse/intro/) is not supported on armv8.0. -- This is an automated message from the Apache Git Service.
