However, it seems the failing binary is not literally 8.0.1, so the line number might be out of sync. What's the source of the `ghc8.0.1.20161117` you're using? A stacktrace could be a bit better. Below, what I can analyze out of this dump, which isn't that much really. I suspect we'd need an actual coredump. https://github.com/ghc/ghc/blob/ghc-8.0.1-release/rts/sm/GC.c#L818 is an unlikely source of a crash. (But my best guess, based on a snapshot of ghc-8.0 with that date, suggests the affected code is https://github.com/ghc/ghc/blob/58d9f9b7a7f1b4d2c94183b9b9428983e7c83fe9/rts..., which is similarly surprising). If either is accurate, we have a segfault when writing *in the middle* of `gen_workspace *ws`. If the source tree matches commit commit 58d9f9b7a7f1b4d2c94183b9b9428983e7c83fe9, given the type definition in https://github.com/ghc/ghc/blob/58d9f9b7a7f1b4d2c94183b9b9428983e7c83fe9/rts..., the crash is when writing to field `ws->todo_large_objects`, which starts 64 bytes after the start of `ws`. `ws` is 64-bytes aligned, so this is plausible (if `ws->todo_large_objects` points to the beginning of a page). Strangely, no register in the dump has the right alignment to be such a `ws`. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12100#comment:10 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
