#11978: running a profiled build of shake test suite with rts args +RTS -hb -N10 triggers SIGSEGV ---------------------------------+---------------------------------------- Reporter: carter | Owner: Type: bug | Status: new Priority: highest | Milestone: Component: Compiler | Version: 8.0.1 Resolution: | Keywords: Operating System: MacOS X | Architecture: Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: #4820 | Differential Rev(s): Wiki Page: | ---------------------------------+---------------------------------------- Comment (by erikd): My friend `printf` tells me that when the value of `size` is less than `sizeofW(StgThunkHeader)` when the closure type is `WHITEHOLE` which seems legitimate. Since everything seems legitimate, the solution to this may simply be to add a check: {{{ if (size > sizeofW(StgThunkHeader)) { for (i = 0; i < size - sizeofW(StgThunkHeader); i++) { ((StgThunk *)(p))->payload[i] = 0; } } }}} @simonmar does this seem right? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11978#comment:11 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
