This problem is only appeared on x86. It doesn't appear on my x86-64 Gentoo Linux. It was happened since openssl-0.9.8l-r2, and it was still happened on openssl-0.9.8m. To use revdep-rebuild cannot help anything. My system uses nss_ldap that depends on OpenSSL (libcrypto.so). It uses TLS to connect to LDAP server, so it affects many basic commands. My CFLAGS is "-O3 -march=prescott -pipe -fomit-frame-pointer". To replace it by "-O2 -march=prescott -pipe -fomit-frame-pointer" can fix this problem.

try USE='-sse2'
(In reply to comment #1) > try USE='-sse2' Thanks. I've tested it just now, but the problem is still occured. Since the error is not caused by illegal instruction signal, whether to use SSE2 instruction set is not the problem. As far as I know, Intel provides SSE2 instruction set for 64-bit CPU in x86 mode.
dont bother specifying versions unless you can verify one that actually worked

It's both OpenSSL and zlib compiled with -ftree-vectorize, implied by -O3 that makes things crashy on x86, with gcc-4.4.x.
