So, if the stack pointer checking diff to OpenBSD is correct, and if I'm not running into a completely unrelated problem: does ghc and/or the runtime library sometimes move the system stack pointer to newly allocated/mapped memory? If so, where in the code?
As far as I know GHC shouldn't touch x86-64's $rsp at all; we specifically avoid using it for the STG stack to ease FFI.
Thanks for the information.
Little update, in case anyone is interested: with the latest version of the diff[1] to OpenBSD, out ghc port and all the hs-ports build and work fine. So, yes, bug in the early diff, or solar activity during my tests ;-) Ciao, Kili [1] https://marc.info/?l=openbsd-tech&m=152035796722258&w=2
