[GHC] #10941: Large heap address space breaks valgrind
#10941: Large heap address space breaks valgrind -------------------------------------+------------------------------------- Reporter: nomeata | Owner: Type: task | Status: new Priority: normal | Milestone: Component: Runtime | Version: 7.11 System | Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: None/Unknown Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: #9706 Differential Rev(s): | -------------------------------------+------------------------------------- It seems that programs compiled with a GHC `--enable-large-address-space` (see #9706) no longer run under valgrind, which is a pitty, as that is useful to get more reliable numbers out of nofib. It fails with `internal error: getMBlock: mmap: Invalid argument` This bug is a general “Can we do anything about this”. In particular, is there a possibility to make this a RTS option instead of a compile time option? Or maybe it is possible to talk to the valgrind authors if they can support such large allocations? If neither, can we maybe extend the error message to say “If you are using a tool like valgrind, you might want to recompile the compiler with `--disable-large-address-space.” -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10941 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
