Before applying this modification, when executing the benchmark listed below, a segment fault will be reported because of the out-of-bounds accessing to the packed_weights buffer: ./x16-packw-bench --benchmark_filter=qs8_qc4w_packw_x8c8__reference/sd1x_diffusion/B:8/M:4096/N:4096/K:40/real_time --benchmark_min_time=0.1 Here, the packed_weights buffer is resized to a reasonable size and the error will not be reported.
