#5188: Runtime error when allocating lots of memory ---------------------------------+--------------------------- Reporter: knyblad | Owner: Type: bug | Status: new Priority: low | Milestone: 7.6.2 Component: GHCi | Version: 6.12.1 Resolution: | Keywords: Operating System: Linux | Architecture: x86 Type of failure: None/Unknown | Difficulty: Unknown Test Case: | Blocked By: Blocking: | Related Tickets: ---------------------------------+--------------------------- Comment (by rwbarton): So I investigated further with gdb, and while I no longer have the exact numbers, gmp was indeed asking for an allocation of more than 4095 MB, resulting in `osGetMBlocks(4096)` and an integer overflow when computing `size` resulting in `size = 0`. The fix should be to detect when the computation of `size` will overflow a `size_t`, and report an out-of-memory error if this occurs. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/5188#comment:7 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
