#12549: Panic on ":t datatypeName" ---------------------------------+-------------------------------------- Reporter: johnleo | Owner: johnleo Type: bug | Status: new Priority: normal | Milestone: 8.2.1 Component: Compiler | Version: 8.1 Resolution: | Keywords: Operating System: MacOS X | Architecture: x86_64 (amd64) Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | ---------------------------------+-------------------------------------- Comment (by simonpj): I'm not certain, but I thought that `tc_infer_args` was the only caller of `new_meta_tv_x` which didn't establish the in-scope set. There are lots of `substTyUnchecked` which each need individual attention. I suppose a new ticket that enumerated them would be a good thing. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12549#comment:30 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
