David Binderman <dcb314 at hotmail dot com> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|RESOLVED |UNCONFIRMED Resolution|INVALID |--- --- Comment #22 from David Binderman <dcb314 at hotmail dot com> --- (In reply to Jakub Jelinek from comment #20) > trying to ensure the reduction doesn't introduce uninitialized var uses > which weren't there before I was also thinking this myself, so I went back to the original test case I reported, before any reduction. This is what I found: $ for i in ~/gcc/results.202205*/bin/gcc; do echo $i; $i -w -ftrivial-auto-var-init=zero -O2 -fno-strict-aliasing bug892.c && (./a.out 1 | fgrep g_50); done /home/dcb36/gcc/results.20220501/bin/gcc ...checksum after hashing g_50 : 646CF84D /home/dcb36/gcc/results.20220508/bin/gcc ...checksum after hashing g_50 : 646CF84D /home/dcb36/gcc/results.20220515/bin/gcc ...checksum after hashing g_50 : C21BF3F9 $ So the original bug is still there and my reduction looks invalid ;-| Snapshots don't exist between 20220508 and 20220515. Is anyone else able to bisect that range ?
