Summary: getUserEntryForID dies

Initial Comment:
The following program dies with an "Illegal
instruction" error:

   module Main where

   import System.Posix.User

   main = do getUserEntryForID 0
             return ()

This is also the case for all the other uids I tried.

I'm running ghc 6.2.1 on Solaris 9.

Fixed in CVS and I expect it to be available in the upcoming 6.2.2. This 
turned out to be much more tricky after all: Solaris defines some functions 
in system headers which the mangler mangled to death when it should leave 
them untouched.

Indeed a bug. The library uses the POSIX-signature which has different 
arguments from Solaris 9 own getpwduid_r. The .hsc-file must be compiled 
with _POSIX_PTHREAD_SEMANTICS like e.g. from libraries/base/cbits/
dirUtils.c.
