hi,

I have tried to train LINE with -train ../../text_article_product_pair.txt -output 2_order_embedding_file -size 200 -order 2 -negative 5 -samples 100 -rho 0.025 -threads 20

and I got the following from gdb

Program received signal SIGSEGV, Segmentation fault. _int_malloc (av=av@entry=0x7ffff7203760 , bytes=bytes@entry=10) at malloc.c:3775 3775 malloc.c: No such file or directory. (gdb) bt

============================================================= and following from valgrind

valgrind: m_mallocfree.c:304 (get_bszB_as_is): Assertion ‘bszB_lo == bszB_hi’ failed. valgrind: Heap block lo/hi size mismatch: lo = 176, hi = 7598532953432678760. This is probably caused by your program erroneously writing past the end of a heap block and corrupting heap metadata. If you fix any invalid writes reported by Memcheck, this assertion failure will

could you have a look about this issue?

Thank you Ken
