I'm sorry for forgetting to include that header.
Meanwhile I've reduced the code further. (And the only C++
left in it is some string handling and output to stdout and
stderr. I hope that doesn't make you too uncomfortable.)
The new code is attached. (Note: This doesn't crash every
time I start it. Percentage varies widely. I suppose this
is an MT issue.)

I have checked the code on a Linux machine. But that had
libcurl 7.18.2 installed. I was unable to reproduce the
issue on that machine.
