 Hi Jerry,
 
 on i686-pc-linux-gnu it's very easy to reproduce here, no special options, both
 3.3 and 3.4. The seg fault happens when _M_group_int tries to use __grouping,
 in particular __grouping.size(). In _M_convert_int, __lc._M_use_grouping is equal
 to 4 (true), but __lc._M_grouping is not a valid string:
 
 (gdb) print __lc._M_grouping.data()
 $3 = 0x0
 
 Paolo.
