#10672: checkProddableBlock crash during Template Haskell linking -------------------------------------+------------------------------------- Reporter: lukexi | Owner: Type: bug | Status: new Priority: high | Milestone: 7.10.3 Component: Compiler | Version: 7.10.1 Resolution: | Keywords: Operating System: Windows | Architecture: Type of failure: Compile-time | Unknown/Multiple crash | Test Case: Blocked By: | Blocking: Related Tickets: #9297 #10563 | Differential Revisions: #8237 #9907 | -------------------------------------+------------------------------------- Comment (by lukexi): To anyone else bitten by this: While this is figured out, I'm just stripping out all uses of Template Haskell in my software since I'm only using it for generating lenses. I put up a simple preprocessor here to do that during the build phase https://github.com/lukexi/strip-ths, designed to work with stack or cabal. (this workaround works because, as I mention in the README for the repro,
Everything also works [...] if I just call cabal exec -- ghc app/Main.hs. This is presumably because GHC doesn't try to link cxxylib when it is just compiling the Template Haskell splices, whereas Cabal asks it to. )
