#11123: Arm: checkProddableBlock: invalid fixup in runtime linke --------------------------------+---------------------------------------- Reporter: erikd | Owner: Type: bug | Status: new Priority: normal | Milestone: 8.0.1 Component: Compiler | Version: 7.11 Keywords: | Operating System: Unknown/Multiple Architecture: arm | Type of failure: Building GHC failed Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: --------------------------------+---------------------------------------- Just started getting this in the last week or two, but only just now got a chance to investigate more fully. Any use of GHCi or TH will result in an error like: {{{ ghc-stage2: internal error: checkProddableBlock: invalid fixup in runtime linker: 0x41380050 (GHC version 7.11.20151122 for arm_unknown_linux) Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug Aborted }}} As a consequence, there are now over 500 failing tests on Arm. I thought this may have been a consequence of all the recent work on `rts/Linker.c` so I checked out git commit 20e30d5f3d932d63933 (the one just before the dreaded commit 04e8366608fee4f which seemed to kick off a bunch of heavy rework in this file) but that revision causes another, even more mysterious linking failure. From what I have seen, this only affects 32 bit Arm. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11123 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
