I'm now able to reduce this to a single (very large) file with only a `text` dependency (which is bundled with GHC HEAD nowadays), which can be found [https://gist.githubusercontent.com/RyanGlScott/75e8b0ad7a3995f6877e3e8e2f9a7... here] (since it exceeds Trac's file upload limit). Running `ghci` on this file is enough to make it panic: {{{ $ ~/Software/ghc2/inplace/bin/ghc-stage2 --interactive LibData.hs GHCi, version 8.3.20171004: http://www.haskell.org/ghc/ :? for help Loaded GHCi configuration from /home/rgscott/.ghci [1 of 1] Compiling LibData ( LibData.hs, interpreted ) ghc-stage2: panic! (the 'impossible' happened) (GHC version 8.3.20171004 for x86_64-unknown-linux): getLabelBc: Ran out of labels }}} I've reproduced this with GHC 8.0.2, 8.2.1, and HEAD. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14334#comment:6 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
