Why PQ chunk size > 100 will cause core dumped in search_disk_index?

[stark1092]

hello, I noticed that the max pq chunk size is limited to 100, and when I try to set a bigger chunk size, it will cause core dumped in search_disk_index() function.
Have you encountered this problem？

This problem is solved, the function alloc_aligned() in pq_flash_index.cpp only allocate 25600*sizeof(float) for scratch.aligned_scratch, which limited the pq chunk num must less than 100.
