#13112: Windows 64-bit GHC HEAD segfaults on the code with a lot of TH stuff. ---------------------------------+-------------------------------------- Reporter: awson | Owner: (none) Type: bug | Status: infoneeded 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 Phyx-): @jbransen, yeah we pretty much know that this happens because TH is exceeding the memory model. That's a sort of design issue with TH. But the issue is made worse on Windows because of the extreme waste the runtime linker has when allocating memory. I have a patch that addresses this but I haven't gotten reviews yet. Hopefully it'll be in 8.6 which should make this a bit harder to trigger. I also have further linker changes planned to make this more rare too. But we'll see if I get the time to finish them for 8.6 (and get them reviewed which will likely be the sticking point) -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13112#comment:32 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
