Changes (by rthiemann):

  * status:  infoneeded => new


Comment:

 Ok, some further experiments with other ghc versions than 7.0.4:

 * Using ghc 6.8.3, there is no crash, but the computation is now running
 since 24 hours.
 * Using ghc 7.6.2, a segmentation fault occurs after having produced
 31064352 bytes of output (after 6 minutes of computation)
 * Using ghc 7.6.2 and compiling with -O2, a segmentation fault occurs
 after having produced 53506464 bytes of output (after 4 minutes of
 computation)
 * Using ghc 7.7.20130310, a segmentation fault occurs after having
 produced 39176544 bytes of output (after 6 minutes of computation)
 * Using ghc 7.7.20130310 and compiling with -O2, the program finishes
 without any error after 8 minutes of computation with a peak memory usage
 of 40 GB, having produced 100773712 bytes of output.
