Package: g++-4.7
Version: 4.7.2-5
Severity: normal

Hi,

the test program

#include <locale>
int main(int, char **) { std::locale loc(""); }

gives an error when run under valgrind:

==1792== Invalid read of size 8
==1792==    at 0x56E5388: wcscmp (wcscmp.S:464)
==1792==    by 0x4EA9554: std::moneypunct<wchar_t, false>::~moneypunct() (in /usr/lib/x86_64-linux-gnu/libstdc++.so.6.0.18)

Actually using facets from the locale object leads to a segmentation fault from locale::~locale().

This problem also exists in g++ 4.6, and may exist in 4.8 (not tested).
