[ab] weirdness in the sdl-ttf C library?

[Samium Gromoff]

I kept having a NULL SAP from sdl-ttf-cffi::ttf-Render-UTF8-Solid, so i
instrumented the glue like this:

extern DECLSPEC SDL_Surface * SDLCALL TTF_glue_RenderUTF8_Solid(TTF_Font *font,
                                                                const char 
*text, SDL_Color *fg) {
        SDL_Surface *ret = TTF_RenderUTF8_Solid(font, text, *fg);
        if (!ret) {
                printf("font: %p, text: %s, color: %p, %08x\n",
                       font, text, fg, *fg);
                printf("Oh My Goodness, an error : <%s>\n", TTF_GetError());
        }
        return ret;
}

And as strange as it might seem, i was getting the following:

font: 0x808f6d8, text: Хеймдалльгард, Хлодвиг, color: 
0xb7bedef8, 00ffffff
Oh My Goodness, an error : <>

I.e. the C function signals an error (as per [1]), yet the error description
was not set.

I think this is fishy.
