 When trying to build https://github.com/vimus/vimus I get a GHC panic on a
 specific module:

 {{{
 λ cabal build
 Building vimus-0.2.1...
 Preprocessing library vimus-0.2.1...
 [38 of 39] Compiling Vimus.Command    ( src/Vimus/Command.hs,
 dist/build/Vimus/Command.o )
 ghc: panic! (the 'impossible' happened)
   (GHC version 7.10.2 for x86_64-unknown-linux):
         Loading temp shared object failed: /tmp/ghc17990_0/libghc_39.so:
 failed to map segment from shared object

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

 I don't know why it's only this particular module of this particular
 library that fails.

 I'm running a kernel with GrSecurity and PaX enabled, and am using a
 hardened GCC toolchain (although Gentoo seems to automatically disable PIE
 for Haskell packages).
