 Hi,
 
 The following test case under C locale failed with the errer like
 pkgsrc/editors/poedit.
 
 $ cat test.cxx
 #include <iostream>
 #include <locale>
 using namespace std;
 
 void print_thousands_separator(const char *localestring)
 {
     std::locale loc = std::locale(localestring);
     auto thou_sep = std::use_facet<std::numpunct<wchar_t>>(loc).thousands_sep();
     wcout << "Thousands separator for " << localestring << " is '" << thou_sep << "'" << endl;
     return;
 }
 
 int main() {
     print_thousands_separator("en_US");
     print_thousands_separator("de_DE.UTF-8");
     print_thousands_separator("ja_JP.UTF-8");
     print_thousands_separator("fr_FR.UTF-8");
 }
 $ g++ test.cxx
 $ ./a.out
 Thousands separator for en_US is ','
 Thousands separator for de_DE.UTF-8 is ','
 Thousands separator for ja_JP.UTF-8 is ','
 zsh: segmentation fault (core dumped)  ./a.out
