We use libeay32.dll and ssleay32.dll from https://slproweb.com/products/Win32OpenSSL.html in our applications and we recently moved from version 1.0.2a to 1.0.2g and now on a few machines running a AMD Geode processor we are getting "Unhandled exception at 0x005904dc (libeay32.dll) in Test.exe: 0xC000001D: Illegal Instruction". We ended up building OpennSSL so we could debug into it and found it is failing on "movsd xmm0,mmword" (see below) which the AMD Geode does not seem to support. I have tried "SET OPENSSL_ia32cap=~0x1000000", "SET OPENSSL_ia32cap=~0x2000000", and "SET OPENSSL_ia32cap=~0x7000000"; and nothing seems to change. I may not be using OPENSSL_ia32cap correctly. This happens when calling SSL_CTX_new which then calls RAND_add. Any ideas on the best thing to do? We don't want to have to manage different compiled versions of libeay32.dll and ssleay32.dll if we can help it.
