#8371: ghci byte compiler + FFI crashes when used with embedded R -------------------------------+---------------------------------- Reporter: dsamperi | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: GHCi | Version: 7.6.3 Resolution: | Keywords: Operating System: Linux | Architecture: x86_64 (amd64) Type of failure: GHCi crash | Difficulty: Unknown Test Case: | Blocked By: Blocking: | Related Tickets: -------------------------------+---------------------------------- Comment (by dsamperi): I accidentally replied to you in gmail (sent to ghc-devs) instead of in this comment thread, sorry! Your comment combined with the suggestion that I use ghc-7.7 provides a work-around. I tried disabling R's stack limit checks, but this leads to a segfault. A correct workaround is to use the flag -fno-ghci-sandbox, as this prevents ghci from forking a thread (all computations are run in the main thread). As noted previously R is not thread-safe. This eliminates the "C stack usage" error messages, but there is still a segfault when ghc-7.6.3 is used (and a non-trivial computation is done). Using ghc-7.7 fixes this.
