#5435: GHCi linker should run constructors for linked libraries -------------------------------------+------------------------------------ Reporter: pumpkin | Owner: Type: bug | Status: new Priority: normal | Milestone: 7.8.1 Component: Compiler | Version: 7.2.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Unknown/Multiple Type of failure: None/Unknown | Difficulty: Unknown Test Case: | Blocked By: 3658 Blocking: | Related Tickets: #3658 -------------------------------------+------------------------------------ Old description:
As far as I can tell from my experimentation, any library that contains a function with __attribute__((constructor)) on it won't have its constructor(s) run when loaded, or its destructors run when unloaded. This violates assumptions that some libraries make.
New description: As far as I can tell from my experimentation, any library that contains a function with `__attribute__((constructor))` on it won't have its constructor(s) run when loaded, or its destructors run when unloaded. This violates assumptions that some libraries make. -- Comment (by ezyang): Note that GHC itself uses constructor (but not destructor) for profiling and foreign exports, so at least the constructor half of this problem is important. I'm attaching implementations for ELF and PEi386; Mach-O coming when I get a Mac to do testing on. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/5435#comment:12 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
