Hey all,
I’m trying to compile GHC HEAD (cloning from master) with the `prof` build flavour on a Mac OS X 10.11.6 machine and I have noticed that, despite ghc-stage2 works as expected, when invoked with —interactive it starts before crashing with a segmentation fault:
``` ☁ compiler [master] ⚡ ../inplace/bin/ghc-stage2 --interactive GHCi, version 8.3.20170413: http://www.haskell.org/ghc/ :? for help [1] 79176 segmentation fault ../inplace/bin/ghc-stage2 --interactive ```
Did it happen to somebody else or it’s just me? Shall I try throwing gdb at it to try and see what’s going on?
Hmm, interesting. I've not seen crashes like this locally nor in CI. It would be great if you could try to get some insight. Is this crash perfectly reproducible? It may be worth adding -dcore-lint to GhcStage2HcOpts to ensure the code we are producing is sane. Cheers, - Ben
