mbrtowc(&wc, "", 0, &ps)

[Edmund GRIMLEY EVANS]

I admit I haven't checked the latest glibc from CVS, and I haven't
investigated any databases of bug reports, so I apologise if this is
already well known.

With glibc-2.2.3, mbrtowc(&wc, "", 0, &ps) seems to return 0 instead
of (size_t)(-2). I think this is a bug.

We noticed this because a program stopped working when we tried to use
glibc instead of libutf8_plug.

#include <stdio.h>
#include <string.h>
#include <wchar.h>

int main()
{
  mbstate_t ps;
  wchar_t wc;

  memset(&ps, 0, sizeof(ps));
  printf("%d\n", mbrtowc(&wc, "", 0, &ps));
  return 0;
}
