4.0 branch 20051204, 4.1 20051124
The following code segfaults. Looks like a double delete,
_S_destroy_c_locale() being called twice: first in the regular path of
codecvt.h:codecvt_byname ctor, then a second time when ~codecvt() is
automatically called to clean up the inherited class.
#include <iostream>
#include <stdexcept>
typedef std::codecvt_byname<wchar_t, char, mbstate_t> cvt_byname_t;
int main()
{
cvt_byname_t *cvt;
char name[] = "invalid-loc";
try {
cvt = new cvt_byname_t(name);
} catch (const std::runtime_error& re) {
std::cerr << "successfully catched misnamed locale" << std::endl;
}
}
