Comment(by patperry):

 To run the program, you need sqlite3, BLAS, and LAPACK installed.

 You also need the data file "enron.db" to be in the current directory.
 This file is too large to upload to track, but I am hosting it at
 http://people.seas.harvard.edu/~patperry/enron.db

 Here is how to reproduce the bug:

 download RTSBug.tar.gz (attached, above), and enron.db to the current
 directory

 {{{
 tar xzvf RTSBug.tar.gz
 cd RTSBug
 runhaskell Setup.lhs configure
 runhaskell Setup.lhs build
 cp ../enron.db .
 ./dist/build/rtsbug/rtsbug
 }}}

 You should see output like:
 {{{
 0
 1
 2
 3
 4
 5
 6
 7
 8
 9
 10
 .
 .
 .
 }}}

 The numbers will increase until you get a segfault.  It usually happens
 before 10000.
