Generally, generic x86_64 target should only use sse2. If you're running llvmpipe though, the code will use runtime detection of features for generated code. I have no idea if that code there causing the crash was runtime-compiled by llvm or not. If yes, it could mean there's still bugs with llvm and cpu detection features (detecting this is quite a mess due to the OS having to support it). Albeit your cpu features make no sense at all, you cannot have avx2 but not avx (and you don't have the newer sse flags neither, even for a virtual cpu that is pretty odd supporting avx2 but not these...). Interestingly, xsave isn't listed neither, which is necessary for avx to indicate the OS supports it, suggesting your OS does not. No idea why...
