From 8f16983e89e3c0095de7bdd902e88cc5d5830979 Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Thu, 28 Jun 2007 21:09:44 +0000 Subject: [PATCH] Add a patch for openssl to fix some breakage that happens when compiled with gcc 4.2.0 Note: this does not cover all instances, but it will at least compile. If the broken parts are reached at run time, the program will crash. I wonder whose stupid idea it was to intentionally(!) make programs segfault when they hit something that *might* be unsafe to use.
