Hi, I've posted on this list a couple of weeks ago. GHC 8.4.1+ has enabled dtrace probes on FreeBSD, sadly this caused an issue with GHC's ability to function as a bootstrap compiler to build GHC. 8.4.2 added a flag to disable dtrace support and link the RTS in a way that does not tamper with the bootstrap ability of the compiler. I'd recommand to ship GHC built with --disable-dtrace for the moment. That does not seem to be the case with the GHC that is currently being shipped via `pkg` so people trying to bootstrap their own compiler might run into unpleasant surprises. I've just now submitted a patch to GHC project that fixes this issue and it'll hopefully be available as soon as possible. Kind regards, raichoo
