#7478: setSessionDynFlags does not always work -------------------------------------+------------------------------------ Reporter: edsko | Owner: Type: bug | Status: new Priority: normal | Milestone: 7.8.1 Component: Compiler | Version: 7.7 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Unknown/Multiple Type of failure: None/Unknown | Difficulty: Unknown Test Case: ghc-api/T7478 | Blocked By: Blocking: | Related Tickets: -------------------------------------+------------------------------------ Changes (by thoughtpolice): * cc: simonmar (added) * version: 7.6.1 => 7.7 * milestone: 7.6.2 => 7.8.1 Comment: On my 32bit linux machine (but not 64bit), I see the following test failure in a regular `./validate` run. It fails rather unhelpfully by just saying "phase 'Linker' failed (exitcode = 1)", but after patching the test to use `-v3` verbosity, I get this output: {{{ ... wired-in package ghc-prim mapped to ghc-prim-0.3.1.0-inplace wired-in package integer-gmp mapped to integer-gmp-0.5.1.0-inplace wired-in package base mapped to base-4.7.0.0-inplace wired-in package rts mapped to builtin_rts wired-in package template-haskell mapped to template- haskell-2.9.0.0-inplace wired-in package dph-seq not found. wired-in package dph-par not found. *** Chasing dependencies: Chasing modules from: *C.hs Stable obj: [] Stable BCO: [] Ready for upsweep [NONREC ModSummary { ms_hs_date = 2014-01-21 15:09:29.865159778 UTC ms_mod = main:Main, ms_textual_imps = [import (implicit) Prelude] ms_srcimps = [] }] *** Deleting temp files: Deleting: compile: input file C.hs *** Checking old interface for main:Main: *** Parser: *** Renamer/typechecker: *** Desugar: Result size of Desugar (after optimization) = {terms: 7, types: 7, coercions: 0} *** Simplifier: Result size of Simplifier = {terms: 7, types: 7, coercions: 0} *** Tidy Core: Result size of Tidy Core = {terms: 7, types: 7, coercions: 0} writeBinIface: 1 Names writeBinIface: 12 dict entries *** CorePrep: Result size of CorePrep = {terms: 7, types: 7, coercions: 0} *** Stg2Stg: *** CodeOutput: *** New CodeGen: *** CPSZ: *** CPSZ: *** CPSZ: *** Assembler: /usr/bin/gcc -U__i686 -fno-stack-protector -DTABLES_NEXT_TO_CODE -I. -x assembler-with-cpp -c /tmp/ghc7616_0/ghc7616_7.s -o C.o Upsweep completely successful. *** Deleting temp files: Deleting: /tmp/ghc7616_0/ghc7616_8.c /tmp/ghc7616_0/ghc7616_7.s /tmp/ghc7616_0/ghc7616_6.s Warning: deleting non-existent /tmp/ghc7616_0/ghc7616_8.c Warning: deleting non-existent /tmp/ghc7616_0/ghc7616_6.s link: linkables are ...
