If I use my parser language to simply build up a parser, and then I run
#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 osa1): Thanks for simplifying the code. I made an attempt at removing unboxed sums (and had to remove some unboxed tuples on the way) [https://github.com/andrewthad/corrupted-memory- example/pull/1 here], and that made the bug disappear. So this may be related with unboxed tuples/sums. the parser Can you elaborate on this? What do you mean by building your parser language? Can you share the code? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15038#comment:12 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
