From c8d42b2f1c105706098309644c2aa90ae6a1206f Mon Sep 17 00:00:00 2001 From: Daniel Stenberg Date: Wed, 14 Jul 2010 23:50:01 +0200 Subject: [PATCH] --retry: access violation with URL part sets continued When getting multiple URLs, curl didn't properly reset the byte counter after a successful transfer so if the subsequent transfer failed it would wrongly use the previous byte counter and behave badly (segfault) because of that. The code assumes that the byte counter and the 'stream' pointer is well in synch.
