Still no clues... Anyway, let us modify logging a bit:

void ApproximateChar(LinearPathConsumer& t, Pointf at, int ch, Font fnt, double tolerance)
{
	PAINTER_TIMING("ApproximateChar");
	Value v;
	INTERLOCKED {
		DLOG("==== ApproximateChar " << ch << " " << (char)ch << " " << fnt << ", tolerance: " << tolerance);
		PAINTER_TIMING("ApproximateChar::Fetch");
		static LRUCache<Value, GlyphKey> cache;
		cache.Shrink(500000);
		sMakeGlyph h;
		h.gk.fnt = fnt;
		h.gk.chr = ch;
		h.gk.tolerance = tolerance;
		v = cache.Get(h);
		DDUMP(ValueTo< Vector<float> >(v));
#if 1
		GlyphPainter chp;
		chp.move = chp.pos = Null;
		chp.tolerance = tolerance;
		PaintCharacter(chp, Pointf(0, 0), ch, fnt);
		DDUMP(chp.glyph);
		ASSERT(ValueTo< Vector<float> >(v) == chp.glyph);
#endif
	}
	const Vector<float>& g = ValueTo< Vector<float> >(v);
	int i = 0;
	while(i < g.GetCount()) {
		Pointf p;
		p.x = g[i++];
		if(p.x > 1e30) {
			p.x = g[i++];
			p.y = g[i++];
			t.Move(p + at);
		}
		else {
			PAINTER_TIMING("ApproximateChar::Line");
			p.y = g[i++];
			t.Line(p + at);
		}
	}
}


(If error is here, it should also assert....)
