Submitted a patch with some comments and an update to the sanity check. Current status: - debug runtime seems to work (the program takes too long to run and I killed it after 30 mins or so) - debug + threaded runtime seems to work (did 10 runs with `+RTS -DS -N2`) - debug + prof fails with {{{ Mult: internal error: ASSERTION FAILED: file rts/sm/Sanity.c, line 210 (GHC version 8.7.20180923 for x86_64_unknown_linux) Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug }}} (the PAP invariant bug) - debug + prof + threaded fails with different errors like {{{ Mult: internal error: invalid closure, info=0x53b130 (GHC version 8.7.20180923 for x86_64_unknown_linux) Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug }}} or {{{ Mult: internal error: ASSERTION FAILED: file rts/sm/Evac.c, line 890 (GHC version 8.7.20180923 for x86_64_unknown_linux) Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15508#comment:20 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
