-V0`, although removing `-threaded` is better (single-threaded is easier
to debug).
Good to know!
> Since the problem appears to be related to `StablePtr`s, you might want
to check all the StablePtr-related code for bugs first, e.g. you might
have freed a `StablePtr` before using it. If you still can't find the
bug, and can't reduce the size of your program, but you can make it crash
reliably, then please do submit a bug report with instructions to
reproduce it.
You are lucky, the problem was my mistake. Due to wrong alignment I peeked
the StablePtr from the wrong address. It had nothing to do with the memory
warnings from GHC.
