Ooops :) Missed that part. You are (of course :) ) correct. Must be something else corrupting the descriptor when calling iconv repeatedly.

Since outleft is set to the 32k size, iconv() won't convert past 32k anyway, will it? So, unless I'm very confused, the program that I posted as a sample (which seems to be what you're referring to) won't ever overwrite memory that it shouldn't.... It's true that there might be input that doesn't get translated (if the parameter is longer than what will fit into the output buffer) but I don't see how it could overwrite another area of memory...
