Segmentation fault when building SIFT1B

[GaryLee1101]

When I constructing the index for SIFT1B, the process consistently encounters a Segmentation fault after approximately 20 hours of operation.

I suspect the recurring Segmentation fault might be related to memory constraints, but I have allocated 512GB of memory and 32 cores in PVE for this container. Interestingly, even when using the learning subset of SIFT1B, which contains only 100 million vectors, the same issue occurs.

Here is my build script:

I found use python script to build the index worked, but searching stage still occurred error
