--- Comment #5 from Hein-Pieter van Braam <hp at tmm dot cx> --- I can build the file I reported #84881 on with the following extra options: -O3 -fno-tree-fre -fno-tree-dominator-opts -fno-tree-copy-prop -fno-tree-ccp -fno-code-hoisting -fno-tree-pre -fno-tree-vrp Perhaps that can help nailing down this issue?
