#2970: Out of boundary access with STLPort

     Type:  Bugs          |      Status:  new         
Milestone:  Boost 1.39.0  |   Component:  lexical_cast
  Version:  Boost 1.38.0  |    Severity:  Problem     
 Keywords:                |  
--------------------------+-------------------------------------------------
 In lexical_cast.hpp, line 519, it is assumed that empty strings end with a
 null char, but this is not true with STLPort :

 {{{char last_grp_size = grouping[0] <= 0 ? CHAR_MAX : grouping[0];}}}

 {{{grouping[0]}}} has an undefined value when {{{grouping}}} is empty. I
 propose this to fix it :

 {{{char last_grp_size = grouping_size == 0 || grouping[0] <= 0 ? CHAR_MAX
 : grouping[0];}}}
