There are also some other quick things you could try (unless you've done that already), e.g. making sure that all C code is compiled with `-g`, and use gdb to attach to the dying process (or the `core` dump file that your OS may write when the segfault happens) and use `bt` to check if the segfault is actually in the Haskell runtime or not. And then of course, if your code is open-source, you might also be able to provide it as a whole before putting in the effort to minimise it. Niklas On 03/02/17 15:19, Dennis Raddle wrote:
You are right, I should try to construct a minimal example. I was hoping there might be some bit of information that could guide me in what to try, as far as taking my rather large program as-is and varying it. Constructing a minimal example will be, potentially a lot of work and may not even segfault -- but that is how it works, you are right, one must provide a minimal example or at least some actual code.
