The first part is generated by glibc.  It means the program has memory 
handling problems and corrupted memory.  The default action is to 
terminate the process using SIGABRT.  It seems the program intercepted

probably ignore this, so, find the memory corruption.

Try running the code under valgrind.  If this doesn't work you'll have 
to run the program under gdb or look at the core file with gdb and see 
which memory blocks are affected.  The track down where this memory is
