Could you add these DLOGs

struct GlyphKey {
	Font   fnt;
	int    chr;
	double tolerance;
	
	bool operator==(const GlyphKey& b) const {
		DLOG("*** operator==");
		DDUMP(fnt);
		DDUMP(b.fnt);
		DDUMP(chr);
		DDUMP(b.chr);
		return fnt == b.fnt && chr == b.chr && tolerance == b.tolerance;
	}
	unsigned GetHashValue() const {
		return CombineHash(fnt, chr, tolerance);
	}
};

struct sMakeGlyph : LRUCache<Value, GlyphKey>::Maker {
	GlyphKey gk;

	GlyphKey Key() const     { return gk; }
	int      Make(Value& v) const {
		GlyphPainter gp;
		gp.move = gp.pos = Null;
		gp.tolerance = gk.tolerance;
		DLOG("*** Make");
		DDUMP(GetHashValue(gk));
		DDUMP(gk.fnt);
		DDUMP(gk.chr);
		PaintCharacter(gp, Pointf(0, 0), gk.chr, gk.fnt);
		int sz = gp.glyph.GetCount() * 4;
		v = RawPickToValue(pick(gp.glyph));
		return sz;
	}
};

void ApproximateChar(LinearPathConsumer& t, Pointf at, int ch, Font fnt, double tolerance)
{
	PAINTER_TIMING("ApproximateChar");
	Value v;
	INTERLOCKED {
		DLOG("==== ApproximateChar " << ch << " " << fnt);
		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;
		DDUMP(GetHashValue(h.gk));
		v = cache.Get(h);
	}
#if 0
	GlyphPainter chp;
	chp.move = chp.pos = Null;
	chp.tolerance = tolerance;
	PaintCharacter(chp, Pointf(0, 0), ch, fnt);
	const Vector<float>& g = chp.glyph;
#else
	const Vector<float>& g = ValueTo< Vector<float> >(v);
#endif
	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);
		}
	}
}


then bring it into error state, send me the screenshot and .log?

Thanks,

Mirek
