--- Comment #9 from Tang, Feng <feng.tang at intel dot com> --- For original report https://lore.kernel.org/lkml/202301170941.49728982-oliver.s...@intel.com/t/, it was reported by Sang Oliver from 0Day team, but I failed to add him too cc (probably due to he is not registered in this bugzilla system?), so I will try to gather some info (some from Oliver's report, some from my local system when it can't be found from Oliver's report) gcc version: gcc-11 (Debian 11.3.0-8) 11.3.0 gcc (Ubuntu 11.3.0-1ubuntu1~22.04) 11.3.0 Platform: QEMU Preprocessing file: page_alloc.i (attached) gcc options: from page_alloc.s(got from 'make ARCH=i386 mm/page_alloc.s') # GNU C89 (Ubuntu 11.3.0-1ubuntu1~22.04) version 11.3.0 (x86_64-linux-gnu) # compiled by GNU C version 11.3.0, GMP version 6.2.1, MPFR version 4.1.0, MPC version 1.2.1, isl version isl-0.24-GMP # GGC heuristics: --param ggc-min-expand=100 --param ggc-min-heapsize=131072 # options passed: -mno-sse -mno-mmx -mno-sse2 -mno-3dnow -mno-avx -m32 -msoft-float -mregparm=3 -mpreferred-stack-boundary=2 -march=i686 -mstack-protector-guard-reg=fs -msta ck-protector-guard-symbol=__stack_chk_guard -mindirect-branch=thunk-extern -mindirect-branch-register -O2 -std=gnu90 -fno-strict-aliasing -fno-common -fshort-wchar -fcf-prot ection=none -freg-struct-return -fno-pic -ffreestanding -fno-asynchronous-unwind-tables -fno-jump-tables -fno-delete-null-pointer-checks -fno-allow-store-data-races -fno-reo rder-blocks -fno-ipa-cp-clone -fno-partial-inlining -fstack-protector-strong -fno-omit-frame-pointer -fno-optimize-sibling-calls -fno-stack-clash-protection -fno-inline-func tions-called-once -fno-strict-overflow -fstack-check=no -fconserve-stack -fprofile-arcs -ftest-coverage -fno-tree-loop-im -fsanitize=bounds -fsanitize=shift -fsanitize=unrea chable
