Package: locales
Version: 2.5-11
Severity: important
Hello
I encountered following error when calling
std::locale loc("");
in a simple c++ program:
loc.cc:
---------------------->%-------------------
#include <iostream>
#include <locale>
int main(int argc, char* argv[])
{
try
{
std::ios::sync_with_stdio(false);
std::locale loc(argc > 1 ? argv[1] : "");
std::cout << loc.name() << std::endl;
}
catch (const std::exception& e)
{
std::cerr << e.what() << std::endl;
}
}
----------------------%<-------------------
When compiled with
$ g++ --version
g++ (GCC) 4.1.3 20070601 (prerelease) (Debian 4.1.2-12)
and executed on my system it produces the following
error message:
$ ./loc ""
locale::facet::_S_create_c_locale name not valid
$ echo $LANG; ./loc $LANG
de_DE.UTF-8
locale::facet::_S_create_c_locale name not valid
This is in contrast to:
$ /usr/sbin/validlocale ""
locale '' valid and available
$ /usr/sbin/validlocale $LANG
locale 'de_DE.UTF-8' valid and available
Requesting the 'C' locale works:
$ ./loc C
C
I report this bug here for package locales because I'm not sure if it has to
do with some misconfiguration of my systen, which I'm not aware of.
I tried dpkg-reconfigure locales and it built the selected locales
afterwards. Here the output of locale -a:
$ locale -a
C
de_DE.utf8
en_GB.utf8
en_US.utf8
POSIX
If it is not a configuration issue, I suspect the bug in libstdc++6 or libc6.
This does not happen in etch.
Additional informations:
$ dpkg -l libstdc++6*
