openwrt/package/openssl/patches/180-gcc_breakage.patch
Felix Fietkau 8f16983e89 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.

Patch taken from http://www.mail-archive.com/openssl-dev@openssl.org/msg22667.html
