The net effect of consuming one element and adding two is to add one.
The code looks correct to me.

Hi,
I'm checking the cff_decoder_parse_charstrings function in cffgload.c
of FT239.
According to CFF technical note #5177, operator "dup" should
consume one element and put two elements to arguement stack:
dup any dup(12 27) any any
But in cff_decoder_parse_charstrings, the codes like this:
case cff_op_dup:
FT_TRACE4(( " dup\n" ));
args[1] = args[0];
args++; //should be args+=2?
break;
Only one element put to arguement stack.
Is this a bug?
FT2310 is the same.
