#10672: checkProddableBlock crash during Template Haskell linking -------------------------------------+------------------------------------- Reporter: lukexi | Owner: Type: bug | Status: new Priority: high | Milestone: Component: Compiler | Version: 7.10.1 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 -------------------------------------+------------------------------------- When compiling an executable that uses Template Haskell against a library that contains C++ code, GHC crashes: {{{ [2 of 2] Compiling Main ( app\Main.hs, dist\build\main\main- tmp\Main.o ) ghc.exe: internal error: checkProddableBlock: invalid fixup in runtime linker: 0000000000360564 (GHC version 7.10.1 for x86_64_unknown_mingw32) Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug }}} I've boiled this down into a minimal reproduction of a library that includes a .cpp file, and an executable that depends on it. To test: {{{ git clone https://github.com/lukexi/cxx-link-fail-repro cabal run }}} The crash does not occur in the repro unless I use C++ exceptions in the library, and use Template Haskell in the executable, but in the project I boiled this down from (http://github.com/lukexi/bullet-mini) the problem occurs even with {{{cc-options: -fno-exceptions}}}. Some more details are at https://github.com/lukexi/cxx-link-fail-repro The platform is Windows 8.1 under MSYS2 (GHC is still using its inbuilt mingw). I've also tried 7.10.2-RC1 with the same result. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10672 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
