Comment:

 Sometimes I get "Bus Error" or "Segmentation Fault" as the last action of
 a ghc call (i.e. after deleting temp dirs), although everything was
 processed correctly.

 These failures can also be seen in http://www.informatik.uni-
 bremen.de/agbkb/forschung/formal_methods/CoFI/hets/solaris/ghcs/ghc-6.12.3-tests.log.gz
