--- Comment #5 from Jiri Slaby <jirislaby at gmail dot com> --- (In reply to Jakub Jelinek from comment #4) > What gcc options are you using on the preprocessed source to trigger this? By default this: gcc-6 -nostdinc -fno-strict-aliasing -fno-common -std=gnu89 -mno-sse -mno-mmx -mno-sse2 -mno-3dnow -mno-avx -m64 -falign-jumps=1 -falign-loops=1 -mno-80387 -mno-fp-ret-in-387 -mpreferred-stack-boundary=3 -mskip-rax-setup -mtune=generic -mno-red-zone -mcmodel=kernel -funit-at-a-time -maccumulate-outgoing-args -pipe -fno-delete-null-pointer-checks -O2 --param=allow-store-data-races=0 -fstack-protector -Wno-unused-but-set-variable -fno-omit-frame-pointer -fno-optimize-sibling-calls -fno-var-tracking-assignments -fasynchronous-unwind-tables -pg -mfentry -fno-inline-functions-called-once -fno-strict-overflow -fconserve-stack -fsanitize=kernel-address -fasan-shadow-offset=0xdffffc0000000000 --param asan-stack=1 --param asan-globals=1 --param asan-instrumentation-with-call-threshold=10000 -fsanitize-coverage=trace-pc -S -o - af_netlink.i And this simplified one produces the same around the call: gcc-6 -nostdinc -O2 -std=gnu89 -fsanitize=kernel-address -fasan-shadow-offset=0xdffffc0000000000 --param asan-stack=1 --param asan-globals=1 --param asan-instrumentation-with-call-threshold=10000 -fsanitize-coverage=trace-pc -S -o - af_netlink.i
