I ticket #8371 I reported a problem using embedded R with ghci (no problem when application is compiled with ghc). The work-around was to use the option -fno-ghci-sandbox with ghci, as this prevented ghci from starting a new thread (R is not thread-safe). This worked fine with pre-release ghci 7.7 (built from source using BuildFlavour = quick), but now I get a segfault on startup using ghci 7.8.2, suggesting that the behavior of -fno-ghci-sandbox may have changed, perhaps because of the way the Linux binary distribution was built. Has the behavior of -fno-ghci-sandbox changed, or could it have been changed because of the way the Linux binary distribution was built? BTW, I would have posted this as a follow-up to the ticket but I forgot my password. How does one reset the password on the ticket tracker site? Thanks, Dominick
