Summary: libcurl v7.24 exits with err 104 while connectin https host

Initial Comment:
At my work I have HTTP-proxy with pre-authorization to access internet. To skip manual authorization I use curl under Cygwin to send auth-form to server.
Recently after an update of Cygwin to 1.7.11 this script has appeared to be broken - curl exits with err 104. After investigation a test script was simplified to
curl -3 -k https://proxy.lan.rarus.ru/BM-Login/?\"http://ya.ru/\" --trace - -D -
to reproduce the error.

Also I discovered that libcurl update to v7.24 (was v7.20) caused this behavior. After manual rollback libcurl-4.dll to previuos version test-script works well.

Message:
Can you please show us the full output you get when you use -v ? There's no
return code 104 in curl/libcurl so it would indicate something truly
weird.

I can't repeat this problem on Linux.
