> Hi,
> I'm trying to modify and run the following sample.cc program to create a table with multiple range partitions via multiple calls to add_range_partition() and the program got a Segmentation fault. 
> On the other hand, if I call add_range_partition() once and the program runs fine.  
> So I'm wondering if calling add_range_partition() multiple times for a single table is supported or not?  This makes it useful when trying to partition the range on multiple primary key columns, e.g. on (key, int_val).
> Thanks.
