#13112: Windows 64-bit GHC HEAD segfaults on the code with a lot of TH stuff. ---------------------------------+-------------------------------------- Reporter: awson | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.1 Resolution: | Keywords: Operating System: Windows | Architecture: x86_64 (amd64) Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | ---------------------------------+-------------------------------------- Comment (by RyanGlScott): OK. The reason I ask is that another user recently reported experiencing a segfault on 64-bit Windows (#14089), and while I haven't tried reproducing the exact issue myself due to the sheer number of dependencies, the heavy use of Template Haskell in their project makes me wonder if this issue is the underlying culprit. Unfortunately, GHC 8.2.1 seems to have made it more difficult to trigger the particular case of `language-c-quote` giving a segfault. It seems doubtful that the issue just magically cured itself in the meantime, since the discussion above strongly suggests that we'll need to change the way GHC allocates memory on Windows to properly fix this. It would be nice if there were a minimal, dependency-less way of reproducing this so that we could continue investigating. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13112#comment:13 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
