ghc-stage2 —interactive segfaults on Mac OS X 10.11.6 (build flavour = prof)

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? Thanks, Alfredo
