[GHC] #8866: scavenge_stack: weird activation record found on stack on "cabal install -j"

#8866: scavenge_stack: weird activation record found on stack on "cabal install -j" ----------------------------------+---------------------------------- Reporter: adinapoli | Owner: Type: bug | Status: new Priority: normal | Milestone: 7.8.1 Component: Build System | Version: 7.8.1-rc2 Keywords: | Operating System: MacOS X Architecture: x86_64 (amd64) | Type of failure: Runtime crash Difficulty: Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | ----------------------------------+---------------------------------- Hello everyone, sorry if this was reported somewhere else. I know that the dreadful "scavenge_stack" is nothing new, but it's the first time I see it on Mac OS X (I'm on Maverick, OS X 10.9.2). This is a "stacktrace" of the problem. It seems to happen almost consistently if I try to do a parallel installation: {{{ [hsenv]☁ ~HSENV cabal install -j snap Resolving dependencies... Configuring HUnit-1.2.5.2... Downloading MonadRandom-0.1.13... Downloading logict-0.6.0.2... cabal: internal error: scavenge_stack: weird activation record found on stack: 415597384 (GHC version 7.8.0.20140228 for x86_64_apple_darwin) Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug [1] 2328 abort cabal install -j snap [hsenv]☁ ~HSENV }}} The concerning thing is that it doesn't seem to be deterministic. After issuing that command, I have tried again and it worked this time: {{{ [hsenv]☁ ~HSENV cabal install -j snap Resolving dependencies... Configuring HUnit-1.2.5.2... Downloading MonadRandom-0.1.13... Configuring SHA-1.6.4... Downloading logict-0.6.0.2... Downloading process-1.1.0.2... [...] }}} It seems to happen with every package and I have tried to install snap just for the sake of reproducing it. Thanks! ps.

#7730: :info and polykinds --------------------------------------------+------------------------------ Reporter: monoidal | Owner: archblob Type: bug | Status: new Priority: normal | Milestone: 7.10.1 Component: Compiler (Type checker) | Version: 7.6.2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: None/Unknown | Unknown/Multiple Test Case: | Difficulty: Unknown Blocking: | Blocked By: | Related Tickets: #8776 --------------------------------------------+------------------------------ Comment (by goldfire): I don't have a strong opinion here (about the extra tags in `IfaceSyn`). After the type/kind merge, these tags would become visible vs. invisible instead of type vs. kind. The same change is happening in many other places throughout GHC. This actually makes good sense -- in the use case at issue in this ticket, you don't actually care what a thing classifies; you care whether or not it should be printed. Because these two distinctions line up at the moment, it's not worth bothering to separate them. So, by all means go ahead with, e.g., Simon's plan. I'll change it to visible/invisible when I merge. :) And, as for Andrei's offer for help: Thanks. At this point, work is stalled somewhat as I'm racing down the Haskell Symposium deadline (May 12) for two papers I'm working on. But, I'm hoping to have something ready for POPL on July 6 about the type/kind merge. Things are in a bit of a messy state at the moment and it's hard for me to see how to integrate another set of hands, but I'll keep your offer in mind -- I do appreciate it. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/7730#comment:32> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler
