#15105: `typecheckModule` from GHC API crashes on MacOS for files with TH ----------------------------------------+---------------------------------- Reporter: harpocrates | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: 8.6.1 Component: GHC API | Version: 8.4.2 Keywords: | Operating System: MacOS X Architecture: Unknown/Multiple | Type of failure: Runtime crash Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: ----------------------------------------+---------------------------------- I believe this is the same issue that is causing manually built `haddock` and `doctest` to crash on MacOS when fed TH (originally reported https://github.com/haskell/haddock/issues/767 and https://github.com/sol/doctest/issues/199). I've attached a minimal program that uses the GHC API and exhibits the same problem. {{{ $ ghc-8.4.2 -package ghc -package containers -package ghc-paths Prog.hs [1 of 1] Compiling Main ( Prog.hs, Prog.o ) Linking Prog ... $ ./Prog Main-no-TH.hs -package template-haskell $ ./Prog Main-TH.hs -package template-haskell Prog: lookupSymbol failed in relocateSection (RELOC_GOT) /usr/local/lib/ghc-8.4.2/integer-gmp-1.0.2.0/HSinteger-gmp-1.0.2.0.o: unknown symbol `___gmp_rands' Prog: Prog: unable to load package `integer-gmp-1.0.2.0' }}} In case it isn't clear, I do not expect `Main-TH.hs` to crash `Prog`. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15105 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
