#12527: GHC segfault while linking llvm-general while compiling a file using Template Haskell -------------------------------------+------------------------------------- Reporter: HMPerson1 | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.10.3 Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: Compile-time Unknown/Multiple | crash Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- If I have a file {{{#!hs -- Lib.hs module Lib where [d| foo = 1 |] }}} and I add `llvm-general` as a dependency, compiling with -v yields the attached log, followed by `segmentation fault (core dumped)`. Investigating with gdb, the back trace is {{{ ... Loading package llvm-general-3.5.1.2 ... linking ... Thread 1 "ghc" received signal SIGSEGV, Segmentation fault. 0x000000004490f604 in ??
