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

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).
