I am trying to build GHC on NetBSD/amd64.
First, I built GHC-6.12.3 by porting from OpenBSD/amd64.
After that, trying to build several versions (6.12.3, 7.0.4, 7.4.2) of
GHC by the stage2 compiler.
Build itself succeeded and compiling by the ghc seems no problem so far.
However, ghci (all versions) crashes always by segmentation fault.

$ ghci
GHCi, version 7.4.2: http://www.haskell.org/ghc/ :? for help

backtrace by gdb shows only "s2xW_info ()".
ktrace (kernel trace) output is as follows.

What should I check next?
I expect the dynamic linker needs something specific NetBSD/amd64, but
it's hard to tell exactly what. Someone needs to debug the failure and
analyse the problem.
Cheers,
Simon
