Are you absolutely sure the headers weren't in fact being larger for each
time the request was re-sent?

I checked this out, in curl_open() in url.c where the whole Urldata struct is
malloc()ed and memset() to zero (including the header_size field).

The header_size field is then increased on two places in _Transfer() (now
placed in transfer.c, previously in highlevel.c).

Finally, it is read in curl_getinfo() in getinfo.c. I can't see where in this
chain, it would get a modified value.

What if you show the headers, would that bring any clues?

It is not a known problem but I can't find where this flaw would be!
