Hi Remy, thanks indeed for your quick answers...

In fact the code I presented is actually a small project I created just
to figure out what is going wrong. The problem appeared in a larger
project, in which I do use auto_ptr's and try-catch blocks.

The idea is to use 50 or more threads to download chunks of the same
file (segmented doanloading) using IdHTTP's ContentRangeStart and
ContentRangeEnd facility (the server I'm testing my program against
does support this facility).

> How much data are you actually downloading from the URL?

The file I'm testing the project with is 18MB.
