Yes, it helps.
BUT. Now I get the most puzzling error. When I've compiled ghc and try to
run ghci I get a panic saying: unknown symbol `stg_chk_2'. The thing I do
to try to cure this is to add Sym(stg_chk_2) to RTS_SYMBOLS in Linker.c.
Doing that however makes Linker.c uncompilable, with the following error:
../includes/ClosureMacros.h: In function `get_entry':
../includes/ClosureMacros.h:66: warning: cast increases required alignment
of target type
Linker.c: At top level:
Linker.c:347: `stg_chk_2' redeclared as different kind of symbol
../includes/StgMiscClosures.h:279: previous declaration of `stg_chk_2'
plus a bunch of warnings.
Help appreciated.
