It seems there may be an issue with GCC. After searching the GCC bug tracker, I
found some similar reports, such as Bug 101941 [1]. However, since Bug 101941
was resolved in GCC-12.1, this appears to be a new or related issue.
It’s worth noting that this problem can be temporarily addressed with a code
adjustment [2], which might help in investigating the root cause more
effectively.
