 It's mostly a http://www.haskell.org/pipermail/ghc-
 devs/2014-March/004363.html
 rechecked on ghc-7.8.1:

 I attempted to leave original packages as-is.

 Steps to reproduce:

 {{{
 $ cd /tmp/
 $ wget -c http://code.haskell.org/~slyfox/selfcontained-eater-
 ghc-7.8-rc2.tar.gz
 $ tar -xzf selfcontained-eater-ghc-7.8-rc2.tar.gz
 $ cd selfcontained-eater-ghc-7.8-rc2
 $ ./mk.sh
 ...
 [279 of 452] Compiling Text.Highlighting.Kate.Syntax.Asp ( highlighting-
 kate-0.5.6.1/Text/Highlighting/Kate/Syntax/Asp.hs, highlighting-
 kate-0.5.6.1/Text/Highlighting/Kate/Syntax/Asp.o )
 stack overflow: use +RTS -K<size> to increase it
 }}}

 I did prepare this testcase for ghc-7.6.3 where it failed only on last 452
 module.
 '''./mk.sh''' is a dumb script calling '''ghc -O2''' + cabal-generated
 bits.
