#15038: Memory Corruption (strange closure type) -------------------------------------+------------------------------------- Reporter: andrewthad | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: 8.6.1 Component: Compiler | Version: 8.4.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: Runtime crash | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by andrewthad): I have gotten it a little smaller. I've removed some functions from `Packed.Bytes.Parser`, and there are also no more levity polymorphic functions. Reminder about weird things: 1. Problems only happen when using `cabal` or `stack` to build, not when using ghc on its own. 2. Collapsing all modules into a single module (which affects inlining) makes the crash disappear. 3. This happens with `-O0` and `-O2`. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15038#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
