Access violation with SDL_RenderText

Hi!
I'm doing some GUI stuff with SDL and I got those constantly changing
values that I need to draw on the screen. The idea (if you don't know SDL)
is that you create a new surface (a bitmap) every time the value changes,
draw it to the screen and then delete the bitmap after drawing.
In pseudo code:
' surface = RenderText(value); // <- This function returns a pointer to a
new surface (a struct)
' DrawSurface(surface);
' UpdateScreen();
' FreeSurface(surface);
Now that works so far. The problem is that my program crashes after some
time - about two minutes when I'm constantly moving the mouse, forcing the
GUI to redraw (access violation in the RenderText() line). Memory usage
goes up a little, about 4k every 10-15 seconds, which makes me a bit
suspicious, since I'm not newing anything at all, besides the surface I
get returned from RenderText() which I delete anyway, using the
FreeSurface() function.
So my question: Has anybody of you had this problem? Or any ideas? Could
that be a GC issue? Maybe the GC wants to free something that doesn't
exist anymore? I have no idea what's going wrong, so if someone could give
me a hint I'd be very glad.
