 I have this project https://github.com/flip111/ghc-runtime-bug1 When i
 execute the following commands:


 {{{
 stack clean
 stack build
 stack build --ghc-options '-j4 -O0 -rtsopts=all -fprof-auto -fprof-auto-
 calls -fprof-cafs' --executable-profiling
 stack exec vfix -- +RTS -hr -sstderr
 }}}

 After the compilation messages i get the following error:


 {{{
 vfix: internal error: Invalid object *c in pop()
     (GHC version 8.4.3 for x86_64_unknown_linux)
     Please report this as a GHC bug:
 http://www.haskell.org/ghc/reportabug
 Command terminated by signal 6
 }}}
