The culprit is in training/wordlist2dawg.cpp.  I think it has something to do with the memory allocation, that looks insane.

    EDGE_ARRAY dawg;
    inT32 max_num_edges =  100000000;
    inT32 reserved_edges =  1000000;

    dawg = (EDGE_ARRAY) Emalloc(sizeof (EDGE_RECORD) * max_num_edges);

It's not dynamically increased to what's needed.  wordlist2dawg works
out of svn, and it looks like they fixed it.

I took off two zeros from max_num_edges and reserved_edges and put it in
/usr/local/bin

I dont know if this is fixed in karmic.
