Martina I think I found it.
It is a bug in hndlib.dll.
In Function: getFParam(...)
Martin creates two GDI resources:
xxdc = initDC()
and
HFONT fnt = CreateFontIndirect(&lf);
but after that he has several RETURNs w/o releasing them.
esp. this that is at the end of WHILE{} loop.

while (len>0) {
...
      fclose(myfile);
	if (subset||type==10)
	    fs.closefile();
			
	//return c_stream.avail_out;
	err = deflateEnd(&c_stream);

/// HERE there is no relase of xxdc and fnt
	if (err!=Z_OK) return err;
            return totalout;
		};

There are other functions too.
