Hello again, I removed my dependency on hmatrix and enabled floating point exceptions via `feenableexcept` hoping to get a call stack showing me where the exception was being raised but alas all I get is
*Main> main ghc: ghc-iserv terminated (-8) Leaving GHCi.
My googling didn’t turn up much but as far as I can tell ghc does *not* handle sigfpe (googling "haskell sigfpe” turns up blog posts on Haskell by someone called “sigfpe”). I think it would be jolly useful to be able to get stack traces of floating point exceptions. How much work would this be? I’d be happy to have a go at it if someone could provide help and guidance. There seems to have been some discussion of it on the ghc-devs mailing list in September (https://mail.haskell.org/pipermail/ghc-devs/2016-September/date.html) but not much in the way of write up.
