#14346: 8.2.1 regression: heap corruption after safe foreign calls -------------------------------------+------------------------------------- Reporter: andrewchen | Owner: (none) Type: bug | Status: infoneeded Priority: highest | Milestone: Component: Runtime System | Version: 8.2.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: Runtime crash | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Changes (by RyanGlScott): * status: new => infoneeded Comment: For whatever reason, I'm not able to reproduce this on either my Ubuntu 14.04 or 17.04 machines with GHC 8.2.1. I'm doing this: {{{ $ ghc -fforce-recomp -threaded bug.c Bug.hs [1 of 1] Compiling Main ( Bug.hs, Bug.o ) Linking Bug ... $ ./Bug }}} It then proceeds to run forever (AFAICT) without hitting any `value mistmatch`es or segfaults. Some questions: 1. What operating system are you using? 2. How can I reproduce this issue //with just GHC//? Please, no instructions involving fancy build tools like `stack`, since if this really is a GHC bug, one should be able to trigger the issue with just GHC. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14346#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
