#10531: modules that can be linked successfully when compiled with optimizations, fail to link with: multiple definition of `__stginit_ZCMain' -------------------------------------+------------------------------------- Reporter: imz | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.6.1 Resolution: | Keywords: Operating System: Linux | Architecture: x86_64 Type of failure: GHC rejects | (amd64) valid program | Test Case: attached Blocked By: | Blocking: Related Tickets: #437 | Differential Revisions: -------------------------------------+------------------------------------- Comment (by rwbarton): With optimization enabled, another identifier `main4` appears in the interface file for A, but only when `-main-is A.main` (`ZCMain_main_info` is a jump to `main4`). So because of this change, a new interface file gets written out, which then has the correct flag hash as well. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10531#comment:8 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
