#9407: Program produces different output when compiled with -O -------------------------------------+------------------------------------- Reporter: arotenberg | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.8.3 Resolution: | Keywords: Operating System: Windows | Architecture: x86_64 (amd64) Type of failure: Incorrect | Difficulty: Unknown result at runtime | Blocked By: Test Case: | Related Tickets: Blocking: | Differential Revisions: | -------------------------------------+------------------------------------- Comment (by simonpj): I can't reproduce the behaviour either, though I am not using precisely 7.8.3. Can other people reproduce? Can you compile both ways with `-dverbose-core2core -ddump-occur-anal -ddump-rule-rewrites -ddump-inlinings` and attach the results?
