[Bug libstdc++/32254] New: std::runtime_error thrown by locale("")

[thanate at asu dot edu]

The following code compiles and run find using my system's
g++-4.1.3 but when compiled with g++-4.2.1 from SVN,
I get

terminate called after throwing an instance of 'std::runtime_error'
  what():  locale::facet::_S_create_c_locale name not valid
Aborted

//-----------------
#include <clocale>
#include <sstream>

int main ()
{
  std::wostringstream os;
  os.imbue(std::locale(""));
  return 0;
}

The only possible explanation is that, at build time, the configury didn't find
the required localedata (at least "de_DE") or other tests failed, and the
generic (instead of gnu) locale model has been selected. In that case the
runtime_error is expected. Can you check that?

umm... I don't know how to check for that. 
But I ran configure with --enable-clocale=gnu.
I posted my build log at
http://mathpost.asu.edu/~thanate/build.log
I'll keep the build dir for a while in case 
you need some more log files.

See this line in the Log:

> checking for C locale to use... generic

That means the configure-time tests for the gnu locale model are not ok and the
generic locale model is selected instead, as a fallback. Can you investigate
whether the 'de_DE' localedata is installed on your system? It's necessary for
those checks. In order to do that you can, for example, run a small C program
that does 'setlocale(LC_ALL, "de_DE")': it must return a non-NULL pointer. On
linux, you can invoke 'localedef --list-archive'. (note that on 4.2.1 vs
earlier releases, even if you pass --enable-clocale=gnu explicitely, the system
is checked for actual support of the locale model, it cannot be forced: that
may explain the unexpected behavior on your side).

localedef --list-archive gave me only one line:

en_US.utf8

I think that's how I set up my system, with only one locale. 
Now I'm not sure why should I have to have de_DE installed
for locale("") to work. But if you want, I can install de_DE
and try again and report back.

Ok, that is it. That locale must be installed because old glibcs had a bug
which showed up clearly with "de_DE" and we must check against it. The docs
explain that, anyway:
