#10174: AArch64 : ghc-stage2 segfaults compiling libraries/parallel -------------------------------------+------------------------------------- Reporter: erikd | Owner: Type: bug | Status: new Priority: normal | Milestone: 7.12.1 Component: Compiler | Version: 7.11 Keywords: | Operating System: Unknown/Multiple Architecture: aarch64 | Type of failure: Building GHC Test Case: | failed Blocking: | Blocked By: Differential Revisions: | Related Tickets: -------------------------------------+------------------------------------- Compiling git HEAD (e02ef0e6d4eefa5f0) on AArch64 hardware using ghc-7.6.3 from Debian as the bootstrap compiler. LLVM is version 3.6.
