12705	wsregex_iterator construction failed	shen_jun_hua@…	John Maddock	"code segment:
 std::wstring str = L""value(\""@methodSubType\"", $method) =\""场地平整\"""";
 static wregex blankPattern(L""^\\s+"");
 wsregex_iterator spaceIter(begin, end, blankPattern);

call stack:
   3.regex_iterator_implementation(const regex_type* p, BidirectionalIterator last, match_flag_type f)
      : base(), end(last), re(*p), flags(f){}
   2.regex_iterator(BidirectionalIterator a, BidirectionalIterator b,

   1.wsregex_iterator spaceIter(begin, end, blankPattern);

in regex_iterator_implementation,  variable re init failed.the m_px of re is 0.
