    Hi,

    First thank you for the great library!

    I’d like to report an issue related to “deadlock” when creating a model with a specific dataset.

    The commands that block forever are:
    waffles_learn train ~/waffles-8354056899231802041.arff -labels 44 reservoir -layers 0
    and
    waffles_learn train ~/waffles-8354056899231802041.arff -labels 44 neuralnet -addlayer 10

    Random forest, for example, runs just fine.

    Operating system:
    Linux ip-172-31-46-245 3.13.0-29-generic #53-Ubuntu SMP Wed Jun 4 21:00:20 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

    waffles_learn: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.24, BuildID[sha1]=9b8c13493387acc1296834da286f34264cb0b365, not stripped

    The datafile is attached.

      Important addition/observation:

      The problem is related to the latest official release: waffles-2014-07-05-source.zip

      The same commands pass with the opt version of the git master.

      The dbg version fails with “Floating point exception (core dumped)”

    Thanks for reporting this problem! I have tracked down the bug, and will fix it as soon as possible. This bug is exposed by line 3567 of your dataset, which contains some missing values. A temporary workaround until I get this fixed may be to remove that line from the data.
