wstring::length() does not work properly with --short-wchar
I'm not sure if this bug is in gcc or glibc. It could be that gcc does not
properly set a certain variable with --short-wchar, or, it could be that glibc
does not properly implement wstring, always assuming a 4-byte wchar_t.
Here is a sample:
// tmp2.cpp
#include <iostream>
int main(int argc, char ** argv)
{
std::wstring wstr = L"Hello, World!";
std::wcout << wstr.length() << std::endl;
return 0;
}
$ g++ -o tmp tmp2.cpp
$ ./tmp
13
$ g++ -o tmp tmp2.cpp --short-wchar
$ ./tmp
19
They should both say 13. ymmv, but the length value given is usually wrong. How
wrong may vary.
