#16186: Segfault when embedding data via file-embed. ---------------------------------+---------------------------------------- Reporter: syd | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.4.3 Resolution: | Keywords: Operating System: Linux | Architecture: Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | ---------------------------------+---------------------------------------- Comment (by syd): I got it down to a much smaller command that still fails: {{{ /nix/store/6j6slxdhbbzxvhkn6yf7afm62r8n9fmf-ghc-8.4.3/bin/ghc --make -hide-all-packages -no-user-package-db -package-db /tmp/nix-build- segfault-0.0.0.drv-2/package.conf.d -package-db dist/package.conf.inplace -package-id base-4.11.1.0 -package-id bytestring-0.10.8.2 src/Lib.hs -j12 +RTS -K [1 of 1] Compiling Lib ( src/Lib.hs, src/Lib.o ) Segmentation fault (core dumped) }}} Also, if I remove the `-j12`, it no longer segfaults. I also tried with `-j2` and that seems to work as well (no segfaults as far as I can tell). I also tried with `-j256` and it segfaults a _lot_ faster. The same goes for `-j4098`. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/16186#comment:6 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
