To debug with GDB, I complied Mighty with "-debug". This changes the
behavior and I got the following error:
mighty-20130905: internal error: ASSERTION FAILED: file rts/sm/MarkWeak.c, line
371
(GHC version 7.7.20130901 for i386_unknown_linux)
Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug
Simon, can you tell what's going on?
