Summary: HTTPs + long URL = segfault

Initial Comment:
When you generate ultra long URL and try to curl HTTPs domain, some memory dump occurs. Test log is attached. Can be tested with following bash script:

#!/bin/bash

num=2048
something_long=$(for i in `seq 1 $num`; do printf "a${i}=${i}"; done)
url="https://google.com/?q=${something_long}"

curl -v -g "${url}"

My system:

Thanks a lot for your report.

However, I just tried your script with curl 7.27.0 and with the current git
HEAD and neither show this problem...
