#10159: cabal build/ghc compiler causes sudden hard reboot of my computer! -----------------------------------------+--------------------------------- Reporter: jamshid | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.8.4 Keywords: | Operating System: Linux Architecture: x86_64 (amd64) | Type of failure: None/Unknown Test Case: | Blocked By: Blocking: | Related Tickets: Differential Revisions: | -----------------------------------------+--------------------------------- I know this sounds pretty nuts, but compiling using ghc, via "cabal build" often suddenly reboots my computer (not the slow "please save your settings" type, but the sudden harsh sound of a relay click and immediate blackness followed by the BIOS screen). This happens somewhat randomly, although the probability of it occurring definitely goes up with a larger codebase. Beyond a certain size, it is pretty much guaranteed to happen. This could possibly have something to do with faulty hardware.... but I am not so sure because.... 1. The reboot only occurs when compiling with GHC. Nothing else (movie watching, compiling with gcc, processing audio, etc) causes this to happen. Furthermore the reboot is as likely to happen on a computer with no other program running as one with tons of background stuff, the ghc build is the only factor. Other than this bug, it is a powerful and reliable machine. 2. The reboot only occurs when I type "cabal build", not "cabal install", even if the project has just been cleaned. If it were just an overheating microprocessor, I would expect the problem to exist in both cases. In fact, as long as I don't type in "cabal build" exactly, I can download large projects (like the ghc compiler source code itself) and build them without a problem. I am even at a loss of what info to give you. I would be happy to supply whatever info you request and even do some debugging. For starters, here is my configuration.... Ubuntu 14.10 Kernel version 3.16.0-31-generic ghc version 7.8.4 cabal-install version 1.22.0.1 using version 1.22.1.1 of the Cabal library CPU- Intel(R) Core(TM) i7-4770 CPU @ 3.40GHz 16GB RAM Motherboard Gigabyte GA-Z87-D3HP I am not sure if logs will be of any use, because I am pretty sure that the sudden nature of the reboot prevents any info from being output.... -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10159 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
