#1 The program crashes with specific parameter settings
I ran the 0.4.2 version of the program with the data distributed in the archive. The program crashed when I ran it on English with the flags set to non-proj and 2nd order.
My machine is a Mac with a PowerPC microprocessor and the java version is "1.5.0_06"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_06-112)
Java HotSpot(TM) Client VM (build 1.5.0_06-64, mixed mode, sharing)
The three other configurations are working fine: (proj, 1st order), (proj, 2nd order), and (non-proj, 1st order)
Here is the printout:
