From caa463bb79a82ac5fce05a0dcf7893d94c84fc5e Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Thu, 27 Jun 2024 17:06:03 -0700 Subject: [PATCH] perf stat: Fix a segfault with --per-cluster --metric-only The new --per-cluster option was added recently but it forgot to update the aggr_header fields which are used for --metric-only option. And it resulted in a segfault due to NULL string in fputs().
