#14192: Change to 1TB VIRT allocation makes it impossible to core-dump Haskell programs -------------------------------------+------------------------------------- Reporter: nh2 | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Runtime System | Version: 8.0.2 Resolution: | Keywords: gdb, | debugging Operating System: Unknown/Multiple | Architecture: Type of failure: Runtime | Unknown/Multiple performance bug | Test Case: Blocked By: | Blocking: Related Tickets: #9706 | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by simonmar): I'm surprised this is an issue, I'm sure I've core-dumped processes with the 1TB address space without any problems. The core files look huge, but they're sparse. I wonder what's being dumped. We could easily add a flag to change the size of the region, but adding a flag to disable the region completely would add a performance overhead because we'd have to check the flag repeatedly in the inner loop of the GC, so I'd really like to avoid that if possible. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14192#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
