7030	GHCi tries to load the text package twice, leading to linking failure	tibbe	simonmar	"For some reason GHC tries to load the text package twice:

{{{
$ ghci -package text
GHCi, version 7.4.1: http://www.haskell.org/ghc/  :? for help
Loading package ghc-prim ... linking ... done.
Loading package integer-gmp ... linking ... done.
Loading package base ... linking ... done.
Loading package array-0.4.0.0 ... linking ... done.
Loading package bytestring-0.9.2.1 ... linking ... done.
Loading package deepseq-1.3.0.0 ... linking ... done.
Loading package text-0.11.2.0 ... linking ... done.
Loading package text-0.11.2.1 ... 

GHCi runtime linker: fatal error: I found a duplicate definition for symbol
   __hs_text_decode_utf8
whilst processing object file
   /Users/tibbe/.cabal/lib/text-0.11.2.1/ghc-7.4.1/HStext-0.11.2.1.o
This could be caused by:
   * Loading two different object files which export the same symbol
   * Specifying the same object file twice on the GHCi command line
   * An incorrect `package.conf' entry, causing some object to be
     loaded twice.
GHCi cannot safely continue in this situation.  Exiting now.  Sorry.

`__hs_text_decode_utf8` is a C function defined in the text package."	bug	closed	high	7.4.3	GHCi	7.4.1	fixed		johan.tibell@…	MacOS X	x86	GHCi crash	Unknown
