Ok, so I'll continue with the reghunt. > So, could you please attach -fdump-tree-optimized -da dumps from both runs? Sure. Even compressed with xz, the tarballs are too large for bugzilla, so I've placed them at https://www.cebitec.uni-bielefeld.de/~ro/files/ti.s2.tar.xz https://www.cebitec.uni-bielefeld.de/~ro/files/ti.s3.tar.xz > Also, check if you are using the same d21 binary, another possibility might be > miscompiled d21. Both the dumps and the objects/assembler output were created with the same d21 binary, just the -fno-checking/-fchecking=1 difference.
