#2970: Out of boundary access with STLPort
--------------------------+-------------------------------------------------
Reporter: Jazz | Owner: nasonov
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];}}}
