#10375: arm: ghci hits an illegal instruction -------------------------------------+--------------------------------- Reporter: erikd | Owner: Type: bug | Status: new Priority: normal | Milestone: 7.10.2 Component: GHCi | Version: 7.10.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: arm Type of failure: GHCi crash | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Revisions: -------------------------------------+--------------------------------- Comment (by erikd): Turning the test case into a script: {{{ data X = A | B deriving Eq A == A }}} and running as: {{{ inplace/bin/ghc-stage2 +RTS -Ds -Di -RTS --interactive < ghci- segfault.script }}} results in: {{{ evaluating unknown closure -- yielding to sched Object 0xb06446a4 = BLACKHOLE(0xb0619a6c) b14ff460: cap 0: thread 17 stopped (yielding) b14ff460: --<< thread 17 (ThreadRunGHC) stopped to switch evaluators b14ff460: cap 0: running thread 17 (ThreadRunGHC) Segmentation fault }}} The `x86_64/linux` version also has this stuff but doesn't segfault: {{{ evaluating unknown closure -- yielding to sched Object 0x7fbea1548150 = BLACKHOLE(0x7fbea1858cb8) 7fbea22fd700: cap 0: thread 19 stopped (yielding) 7fbea22fd700: --<< thread 19 (ThreadRunGHC) stopped to switch evaluators 7fbea22fd700: cap 0: running thread 19 (ThreadRunGHC) 7fbea22fd700: cap 0: thread 19 stopped (yielding) 7fbea22fd700: --<< thread 19 (ThreadInterpret) stopped to switch evaluators 7fbea22fd700: cap 0: running thread 19 (ThreadInterpret) }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10375#comment:8 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
