 I work on a Haskell library interfacing with foreign C++ library. While
 trying to use it in GHCi on Windows 8.1 64bit, I encountered an error
 message that said:

 {{{
 <loading other libraries>
 Loading package library-0.1.0.0 ... <interactive>: Unknown PEi386 section
 name `
 .text$_ZNSt6vectorIcSaIcEED1Ev' (while processing: c:\path\to\file.o)
 ghc.exe: panic! (the 'impossible' happened)
 (GHC version 7.8.3 for i386-unknown-mingw32):
 loadObj "C:\\path\\to\\file.o": failed

 Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug
 }}}

 I've prepared a minimal example triggering this bug and attached it to
 this bug report. On Linux (Arch 64bit), after cabal build and cabal repl
 it behaves as intended:

 {{{
 GHCi, version 7.8.3: http://www.haskell.org/ghc/  :? for help

 final link ... done

 Ok, modules loaded: Example.

 }}}

 However, on Windows 8.1 it crashes while loading object file:

 {{{

 }}}

 Crashing in GHCi means that I cannot use it with programs that contain TH
 splices, what is important for me.
