#8103: Segfault when passing unboxed Float# and Double# across modules ----------------------------------+--------------------------- Reporter: jstolarek | Owner: Type: bug | Status: new Priority: highest | Milestone: 7.8.1 Component: Compiler | Version: 7.7 Resolution: | Keywords: Operating System: Linux | Architecture: x86 Type of failure: Runtime crash | Difficulty: Unknown Test Case: | Blocked By: Blocking: 6135 | Related Tickets: ----------------------------------+--------------------------- Comment (by jstolarek): I just built latest HEAD (a27895b) and I can't reproduce this bug. This time the call looks different from two versions I pasted in the bug report: {{{ ck4: I32[Sp - 8] = stg_bh_upd_frame_info; P32[Sp - 4] = Hp - 4; I32[Sp - 12] = ck6; R1 = AddWraps.foo_closure; F64[Sp - 32] = 0.0 :: W64; I32[Sp - 24] = stg_ap_d_info; F64[Sp - 20] = 1.2 :: W64; Sp = Sp - 32; call stg_ap_d_fast(R1) returns to ck6, args: 24, res: 4, upd: 12; ck6: _sjO::F64 = D1; Hp = Hp + 12; if (Hp > HpLim) goto ckh; else goto ckg; }}} Still, there are references to D1 (but not D2). I'll run more tests tomorrow and if indeed the problem has disappeared I'll add regression test and close this report. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8103#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
