Hi all,I'm trying to step through some ghc code.I am trying to use pprTrace ( 
for the first time ) and I keep getting an error when I use it :I've added it 
to the file ghc/Main.hs and the resulting code is this :
       let argv1' = map (mkGeneralLocated "on the commandline") argv1       
(argv2, staticFlagWarnings) <- pprTrace "argv1 prime" (ppr argv1') $ 
parseStaticFlags argv1'
I want to examine the value of argv1'. After my modification, I go into the 
ghc/ folder and run : 'make'But doing this leads to an error when I try to run 
the program :
      ghc-stage2: panic! (the 'impossible' happened)      (GHC version 
7.11.20150810 for x86_64-unknown-linux): Static flags have not been 
initialised!          Please call GHC.parseStaticFlags early enough.
What am I doing wrong ? Omar Mefire,
