#15571: Eager AP_STACK blackholing causes incorrect size info for sanity checks -------------------------------------+------------------------------------- Reporter: osa1 | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: 8.6.1 Component: Runtime System | Version: 8.5 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: #15508 | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by simonmar): Hmm, I wonder if there's a much simpler way. The AP_STACK entry code simply copies the payload of the object onto the stack, after doing a stack check. So why don't we zero the slop immediately after copying the payload? That way we don't overwrite any data, and we don't need any new objects or stack frames. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15571#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
